Hi @priscilla-glenn, the --core 0
flag directs cutadapt to auto detect and use all available cores. There are multiple places to specify config parameters to Nextflow, the order of their priorities can be found here. Your "28 cores" might likely be overwritten depending on where you specified it.
To further debug the cutadapt timeout issue, you can go to the working directory, e.g. /mnt/md1/Priscilla/SingleCell/scATACpipe/work/b5/ec60d7f751e55ff29b6016de4ba841
, and check out the .command.log
file. You can also share it here.
Thank you. I will try resetting some of the config parameters to see if that helps.
In addition, here is the .command.log file for your reference.
This is cutadapt 3.4 with Python 3.9.1 Command line parameters: --cores=0 -a AGATCGGAAGAGC -A AGATCGGAAGAGC -o R1_Sample_S1_1.barcoded.trimmed.fastq.gz -p R2_Sample_S1_1.barcoded.trimmed.fastq.gz R1_Sample_S1_1.barcoded.fastq.gz R2_Sample_S1_1.barcoded.fastq.gz Processing reads on 32 cores in paired-end mode ... nxf-uiXqo6FQ015ZXvCk4oxA87gZ
My current config file (before adjusting more) params { preprocess = 'default' input_fastq = '/home/blackmonlab/big-storage/Priscilla/SingleCell/MouseSC/scATACpipe_mouse_samplesheet.csv' outdir = './scATAC_mouse2' species_latin_name = 'Mus musculus' ref_fasta_ensembl = 'mus_musculus' split_fastq = false barcode_correction = 'pheniqs' whitelist_barcode = 'assets/whitelist_barcodes' filter = 'both' doublet_removal_algorithm = 'archr' archr_thread = 8 archr_blacklist = false archr_batch_correction_harmony = true filter_sample = false filter_seurat_ilsi = false custom_peaks = false archr_scrnaseq = false archr_scrnaseq_grouplist = false max_memory = '110.GB' max_cpus = 28 max_time = '240.h' }
And here is the .command.run file as well. Please let me know if there any other files that could help with the troubleshooting. Thank you!

Typically, cutadapt
should be very fast. I think next debugging step is to try to run the problematic command directly. Here are how:
cd /mnt/md1/Priscilla/SingleCell/scATACpipe/work/b5/ec60d7f751e55ff29b6016de4ba841
hukai916/cutadapt_xenial:0.1
docker run -it hukai916/cutadapt_xenial:0.1
if you are using docker. Or singularity shell xxx.sif
if you are using singularity
, the xxx.sif
file should be under the work/singularity
directory..command.sh
and run to see if you can replicate the error.Btw, I notice another config /mnt/md1/Priscilla/SingleCell/scATACpipe/Mouse_custom.config
, which might set max_cpus = 32
and override the default?
Thank you.
I went to the working directory cd /mnt/md1/Priscilla/SingleCell/scATACpipe/work/b5/ec60d7f751e55ff29b6016de4ba841
and activated the container for cutadapt successfully. My terminal has (base) root@b407de9f1cc3:/#
on the far left.
I then tried to run the code above from .command.sh
cutadapt --cores=0 -a AGATCGGAAGAGC -A AGATCGGAAGAGC -o R1_Sample_S1_1.barcoded.trimmed.fastq.gz -p R2_Sample_S1_1.barcoded.trimmed.fastq.gz R1_Sample_S1_1.barcoded.fastq.gz R2_Sample_S1_1.barcoded.fastq.gz
However, I get an error stating it cannot find my input file. And when I look in the directory using ls while in the docker container, the files from my original working directory are no longer listed.

As for the Mouse_custom.config, that is the config I generated for this project and in it I stated that max_cpus = 28
Just thought I'd give an update.
I went into the cutadapt.nf code and replaced the option variable with cores=28. However, when I resume the session, while I can see that the command.sh file now states cores=28 instead of cores=0, it still doesn't appear to work. When I first restart the session, on my system monitor, I can see that it starts working and the cores are being used, however, after about five minutes it starts going into a cycle of not finishing cutadapt and the system shows that not much processing is occurring on the cores.
In addition, I ran cutadapt 4.4 outside of scATACpipe to try to get an estimate of how long cutadapt should take on my data and it finished in about 30 minutes.
At this point, I'm not sure why it won't finish cutadapt. So Hopefully getting it to run in the container for cutadapt will allow us to debug the issue.
Thanks,

Hi, I am on vacation and might be slow in response.
To use docker, you need to mount your local folder to the container, check out here. Or, you can run docker command in non-interactive mode without the -it
flag. Let me know if any questions.
Thanks for your help. I was able to mount the folder which held the barcode files (not the pointer files) and run cutadapt. It ran correctly and finished in 25 minutes so I'm not sure why it's not working when I run the full pipeline. At this point I will try to redownload scATACpipe and recreate the config file.
Maybe also try a fresh start by not using the -resume
.
Hi, so I did a fresh start without using resume and no luck.
Though I did not notice the last time I tried to resume and this time with the fresh restart, that my swap memory was suddenly filling up and as soon the swap memory filled, my core usage dropped and the cutadapt started cycling. This only happens in the scATACpipe container as I was successfully able to run the cutadapt container by itself and run cutadapt on my own outside of any container.
I have 32 cores and 130 Gb of memory on my computer. And have 488,981,686 read pairs in my files. Is this a system requirement issue or is there a parameter I could fix for in usage with the scATACpipe container?
Thank you
The resources on your computer should be more than sufficient for cutadapt
. I don't quite understand why the container would not work with the pipeline. I have created a new container using the latest version of cutadapt
(v4.4), do you mind trying to change the following line:
https://github.com/hukai916/scATACpipe/blob/8e0048985ee2e8fc2a466065ec9d96b2de6c9517/modules/local/cutadapt.nf#L12
to container "hukai916/cutadapt:0.1"
, and try again?
Hi, I will try that and let you know how it goes.
Also, I tried running the pipeline on another computer in the lab set to 60 cores and 200 G memory. Again cutadapt failed but this time it gave a different error:
"WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap."
What's interesting is when I watch my system monitor, my memory has not filled up, it's only the swap memory that suddenly is filled and it's my understanding that the computer shouldn't use swap until the memory is filled. So I don't know why its filling the swap instead. Is there anything in the container settings about swap?
One idea I have as I rerun it is to lower the core number to give each core more memory. I'll keep you posted. Thanks for all your help with this.
Good morning, I've just checked the code I ran this weekend and after adjusting the cutadapt pipeline and running lower cores, I received an error in executing the "GET_WHITELIST_BARCODE". I've attached the nextflow log and my config.

Can you try remove the whitelist_barcodes/.nextflow
folder ? the
whitelist_barcodes folder supposes to contain only whitelist barcode files
not any hidden folders.

Okay so cutadapt actually finished! But then of course a new error had to pop up with bwa mem. "[e7/7d7c3b] NOTE: Process SCATACPIPE:PREPROCESS_DEFAULT:BWA_MAP (1)
terminated with an error exit status (1) -- Execution is retried (2)"
I check the command.err and .log and both say
"WARNING: Your kernel does not support swap limit capabilities or the cgroup is not mounted. Memory limited without swap.

and the command.sh files says:

Sorry for the late reply, I am back to work now.
Seems that your bwa_index
folder is empty, by default, if bwa index files are not supplied, scATACpipe will build them using the supplied genome fastq file. Can you check the SCATACPIPE:PREPROCESS_DEFAULT:BWA_INDEX
output first? Let me know if any questions.
Hi, welcome back. I hope you had a great vacation. I tried rerunning the pipeline without supplying any index files so everything would be the default version. I've included a lot below to try to figure out why it's not working. Let me know if you need any other files.
First, here is my config file for this run so it should have created everything itself.
// Save the following configurations into custom.config params { preprocess = 'default' input_fastq = '/home/blackmonlab/Desktop/scATACpipe/scATACpipe/sample_sheet_test_data1.csv' outdir = './MouseSC3' species_latin_name = 'Mus musculus' ref_fasta_ensembl = 'mus_musculus' split_fastq = false barcode_correction = 'pheniqs' whitelist_barcode = '/home/blackmonlab/Desktop/scATACpipe/scATACpipe/assets/whitelist_barcodes' filter = 'both' doublet_removal_algorithm = 'archr' archr_thread = 8 archr_blacklist = false archr_batch_correction_harmony = true filter_sample = false filter_seurat_ilsi = false custom_peaks = false archr_scrnaseq = false archr_scrnaseq_grouplist = false max_memory = '200.GB' max_cpus = 32 max_time = '240.h' }
// Use this command: sudo nextflow run main.nf -c Mouse_custom.config -profile docker,local.
but here is the error again.

When I look at the output for BWA_index the command log seems to have indicated it worked.

Thoughts? and thank you!
Seems that the bwa mem
step is to blame. I suggest the following debugging steps.
cd /home/blackmonlab/Desktop/scATACpipe/scATACpipe/work/8d/b51980964f520ea4ee9555e00a3dfc
hukai916/bwa_xenial:0.1
)the actual commands being executed by this module are (.command.sh):
filename=$(basename bwa_index/*.bwt)
index_name="${filename%.*}"
sample_name=R1_Sample_S1_1.barcoded.trimmed.fastq.gz
outname="${sample_name%%.*}"
outname="${outname#R1_}"
bwa mem -t 32 bwa_index/$index_name R1_Sample_S1_1.barcoded.trimmed.fastq.gz R2_Sample_S1_1.barcoded.trimmed.fastq.gz | samtools sort -@ 32 -m 805306368 -O bam -o ${outname}.sorted.bam
Try run each command at a time, make sure index_name
is correct and the index file is actually there. Let me know,
Thank you. I am actually about to head on vacation now myself for a week so I won't be able to test this out until I get back.
Hi, I'm back in the lab and working on debugging this. When I mount my files to the container, it is unable to use files that are being pointed to by another file and gives the . So, to get around this, I went to the original bwa_index folder at 6c/9d5c273a42ec4f4369368036147c95.
I ran the naming code and everything was correct.
I then went to the folders with the actual sample files at c6/518fd88378bc056f65ec7bf026a2be and ran the following code
bwa mem -t 32 ../../6c/9d5c273a42ec4f4369368036147c95/bwa_index/$index_name R1_Sample_S1_1.barcoded.trimmed.fastq.gz R2_Sample_S1_1.barcoded.trimmed.fastq.gz | samtools sort -@ 32 -m 805306368 -O bam -o ${outname}.sorted.bam
And it ran! I have an output file called "Sample_S1_1.sorted.bam" in my current directory: c6/518fd88378bc056f65ec7bf026a2be
Given this, I'm not sure why when its not in the direct container, it was unable to find the index files. Thoughts?
Hi quick question, I'm going through the pipeline manually now and how was the adapter chosen to be used in cutadapt?
Thanks!
Hi, the adapters used for cutadapt is default to the first 13bp used in Illumina standard adapter. They can be configured to use other sequences here: https://github.com/hukai916/scATACpipe/blob/8e0048985ee2e8fc2a466065ec9d96b2de6c9517/nextflow.config#L31-L32
Thanks hukai916. I'm progressing through the steps well. I'm now at the DEDUP_BAM module and am curious what I should use as the $barcode_tag?
In scATACpipe, the DEDUP_BAM
is called twice. The first run is a rough de-duplication without cell barcode correction, the aim is to find out the inflection point to determine the valid cell numbers. The second run is to deduplicate with the corrected cell barcodes saved in the "CB" tag.
Therefore, for the first run, the barcode_tag
is set to "N/A" while for the second run, it is set to "CB". These will be set automatically if you were able to run the pipeline automatically instead of manually. For your convenience, the corresponding lines are below:
First run: https://github.com/hukai916/scATACpipe/blob/8e0048985ee2e8fc2a466065ec9d96b2de6c9517/workflows/preprocess_default.nf#L159
Second run:
https://github.com/hukai916/scATACpipe/blob/8e0048985ee2e8fc2a466065ec9d96b2de6c9517/workflows/preprocess_default.nf#L229
It is still mysterious to me why you can not run the pipeline automatically in your environment.
Thank you! And I'm not sure either but going through the pipeline step by step has been good for me to learn the process at least. It also means I can more easily go back and adjust any mapping steps as well if need. I'll probably try to rerun the pipeline in the near future but for now, I'll keep doing this.
As for the remove_dup step. I tried running it and ran into this error. Do you know which version of sinto you used?
python3 ../../../remove_duplicate.py --inbam mm39.filtered.bam --barcode_tag "N/A" --outdir ./ --outbam mm39.dedup.bam --nproc 75
Traceback (most recent call last):

^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'sinto.utils' has no attribute 'chunk_bam_by_chr'
Hi, when I investigated Sinto.utils, https://github.com/timoast/sinto/blob/master/sinto/utils.py, I find chunk_bam but nothing called chunk_bam_by_chr. Was this in an older version? Did you create it? Is there a way that I can use this segment of the pipeline and then export the results?
I tried running chunk_bam itself and it froze my computer while creating empty temporary files whose names sometimes started on one chr and ended on another. So not exactly sure what happened but I'm digging into it.
Thanks for all your help.
Hi,
The sinto
is a customized version. When you run the pipeline, the docker container ("hukai916/sinto_kai:0.3") that harbors this customized sinto
will be downloaded automatically. You can find the script here: https://github.com/hukai916/sinto/tree/master/sinto
The function chunk_bam_by_chr
is used for remove duplicates (DEDUP_BAM
module). The chunk_bam
function implemented in the original sinto
package may group multiple chromosome regions into the same chunk, which is not compatible with our multi-processing strategy, therefore, we implemented chunk_bam_by_chr
so that each chunk only come from a single chromosome.
Hi, I downloaded the sinto folder and put it into the same folder with the remove_duplicate.py script. I called it sinto2 and updated the script to import utils from sinto2.
I then tried running the script as shown down below but am getting weird results with chunks to scaffolds and such. Any ideas why this would be or how I should download your version of sinto?
The init.py script is still finding the metadata for "sinto"

Which sinto folder did you download? I assume you are running the script locally, if so, do you have 50 cores (nproc = 50)? Can you share the input bam so that i can try replicatethe issue? Thanks,
Hi, I git cloned sinto from the link you shared and then renamed the sinto folder within that to sinto2 which I copied to my working directory. I then downloaded the remove_duplicates.py script into the same working directory and updated it to import sinto2. My computer has upto 100 cpus available.
Here is a link to the original bam file and the filtered bam I created. https://drive.google.com/file/d/1lc0nscqrh3zWaCfkXUxTpewBKfjPJTj7/view?usp=sharing
Hi, I just wanted to follow up and check if you were able to download the bam file correctly?
Here is a workflow document I have for what I've been doing. https://docs.google.com/document/d/1a6F1WyY4PI8PJtYyo2VBMqJt_Z_mxKELRK8wbBFavDk/edit?usp=sharing
Can you grant me access? Thanks!
Shared!
Thanks! I confirm that I have access to both files now, let me look into it and let you know.
The bam files are too large to download, can you try downsampling it to 10% and share the link? You can use samtools view -b -s 0.1 foo.bam > sampled.bam
for randomly downsampling 10% of the BAM. Thanks,
You should be receiving a notice from google with the new shared files. Thanks!
Hi @priscilla-glenn, I was able to download and downsample your original bam file to 5% for testing purpose. I can repeat what you observed with the custom sinto
(that you saved as sinto2
). If you see info like below:
Processing chunk_chr1_0.0_to_chrJH584295.1_329.3333333333333 ...
Processing chunk_chr1_32525713.166666668_to_chrJH584295.1_658.6666666666666 ...

Processing chunk_chr1_162628565.83333334_to_chrJH584295.1_1976.0 ...
It basically means that you are actually invoking the correct sinto
version. The function chunk_bam_by_chr
would split each chromosome into --nproc
pieces and process every ith piece from each chromosome in one processor. For example, if --nproc 10
, each chromosome/scaffold would be split into 10 pieces. and processor1 would analyze the first piece from each chromosome/scaffold; likewise, processor2 would analyze the second piece from each chromosome/scaffold, and so on. Meanwhile, each parallel job would print out information consisting of the start coordinate of the first chromosome piece and the end coordinate of the last piece that it is processing, which is shown above. Let me know if unclear.
Thank you very much. And so that means the final output is still correct even though the printing in the terminal is as shown above? Or do I need to adjust the code in some way? Thank you so much for your help in this!
Correct, though the printing is sort of confusing, the results should be right, no need to adjust. When the run finishes, you should see a summary info like below.
Soft_clipped (reads): 631524
No corrected barcode (of all paired fragments): 0
Not properly mapped (fragments): 0
Total unique fragments: 20434638
Total duplicate fragments: 194386
Thank you very much, it worked!
On the get_whitelist_barcode.py script, it states """ Given whitelist_barcode folder, index_fastq, outfile_prefix, select the correct whitelist with the highest overlapping fraction. If fraction less than 0.5, exits with error msg. """
Wouldn't you want the barcode_fastq instead of the index_fastq?
The index_fastq
here refers to the fastq file containing the cell barcodes, or called cell index.
Hi, I've tried running scATACpipe and while this time it started without issues, the cutadapt has timed out. I've included my nextflow.log for your convenience as I'm not sure why it was taking so long to run. I did notice one discrepancy where cutadapt said it was trying to use 32 cores (pasted below) even though in my config file I said the max should be 28 cores. So my one guess would be the computer is trying to use 32 cores when I didn't give it access to 32. Would there be a way to fix it so cutadapt is trying to use 32 cores?
Thanks!
