5 years ago Dear Julien,
Could you check that the gene symbols in your expression matrix are unique? Just to make sure that this is not causing your issue. Thanks for your help.
Kindest regards, Bram

5 years ago Dear @bramvds ,
Thanks for your reply. I just checked, all gene symbols in my expression matrix are unique.

5 years ago Hi Julien,
Is there something special with JUN expression across samples/cells? It is discovered by GENIE3/GRNBoost2 as a TF and/or target gene but does not appear in the gene-gene correlation matrix derived from the single-cell expression matrix. This is the cause of the error you get.
Kindest regards, Bram

5 years ago Hi Bram,
Thanks for your reply. I just checked, there is nothing special about JUN expression, at least as far as I can tell. Would it help if I could send you my two input files (expression matrix and "adjacencies.tsv" from the grn step) so that you can see for yourself?
Best, Julien

4 years ago Hi Bram,
I have tried the same commands with another dataset to verify that the error wasn't due to this specific matrix. In fact I get exactly the same error, except that this time the problematic TF is not "JUN" but "SELENOP". I notice that "JUN" and "SELENOP" are each time the first entry of the "target" column from the output file adjacencies.tsv from the grn step. Could it be an issue with the structure of the matrix (i.e. naming or indexing of columns)?
Thanks for your help,
Julien

4 years ago HI Julien,
Just the be sure, could you check your adjacencies file (i.e. the output from the GRN step)? The extension of the file needs to match its format (if fields are separated by commas it needs to be 'csv', if the separator is tab then it should be 'tsv'). Moreover, the file should contain a header as first line:
TF,target,importance
ZNF286B,ZNF286A,210.82799147360737
ZNF286A,ZNF286B,147.96375430051933Kindest regards, Bram

4 years ago Hi Bram,
Thanks for your reply. I have just checked, my file is "adjacencies.tsv" and it is correctly tab-separated: head adjacencies.tsv TF target importance MAF SELENOP 183.99765918421974 MAF RNASE1 175.62542977180237
Anyway, I just managed to run the whole pipeline by using the Python tool with Jupyter, so I guess we can leave this problem unsolved especially if I'm the only person to have encountered it..
Thank you again for all your time!
Best,
Julien

4 years ago I think I've figured out what happened here after running into a similar issue recently. If there are genes present in the network output (adjacencies) that are missing from the gene expression matrix, then this KeyError will occur. This could happen for instance if some further filtering was done after running GRNBoost2, or if the wrong expression matrix was given in the CTX step.

4 years ago Hi,
I am trying to run pyscenic ctx from the output of arboreto_with_multiprocessing.py and I am getting an error that looks related to this one - not sure if it is or not?
My commands are as follows:
python arboreto_with_multiprocessing.py data/merged_all_analysed.loom resources/tfs_list/lambert2018.txt --output results/adjacencies.csv --num_workers 20
pyscenic ctx -o results/reg.csv --annotations_fname resources/motif_annotation/motifs-v9-nr.hgnc-m0.001-o0.0.tbl --num_workers 24 --expression_mtx_fname data/merged_all_analysed.loom --cell_id_attribute CellID --gene_attribute Gene results/adjacencies_arboreto.csv resources/cistarget/hg38__refseq-r80__10kb_up_and_down_tss.mc9nr.feather resources/cistarget/hg38__refseq-r80__500bp_up_and_100bp_down_tss.mc9nr.feather
I am using the same input expression matrix for both commands.
The error I get is as follows:
Traceback (most recent call last): File "/data/user/lucy/py36-v1/conda-install/envs/pyscenic/bin/pyscenic", line 8, in

Do you have any suggestions as to how to fix this?

4 years ago Hi @cflerin,
Just an observation, without knowing anything about the code implementation (part of a team working alongside @lc822 ), could the error be related to the header being used within the pandas hash function?
File "pandas/_libs/hashtable_class_helper.pxi", line 1614, in pandas._libs.hashtable.PyObjectHashTable.get_item
KeyError: 'TF'The reason I ask is that the error complains that a keyError is not found using "TF", but if I look at the tab file above it seems like TF forms part of the header and not a gene.

4 years ago Hi @lc822 , @Acribbs ,
Indeed, it seems like pandas is looking for a gene named "TF", which should be part of the header.
Could you try renaming the file to end with .tsv if it's really tab separated? If your file is actually tab delimited, but named with a .csv extension this will cause an issue with the file delimiter detection, which is based on file extension.
This seems to be a bug in the arboreto script actually, which always uses tab as a separator, while you've requested the output to be comma-separated, and the ctx step is looking for commas. I'll make a fix for this.
Hi, I'm trying to run the pyscenic CLI, I have already managed to run the grn step and I got an output "adjacencies.tsv", but when I proceed to the ctx step I have a KeyError. My command is the following one:
pyscenic ctx --mode dask_multiprocessing --annotations_fname $RESOURCES_FOLDER"motifs-v9-nr.hgnc-m0.001-o0.0.tbl" --num_workers 8 --output $DATA_FOLDER"regulons.csv" --expression_mtx_fname $DATA_FOLDER"exp.csv" $DATA_FOLDER"adjacencies.tsv" $DATABASE_FOLDER"hg38refseq-r8010kb_up_and_down_tss.mc9nr.feather" $DATABASE_FOLDER"hg38refseq-r80500bp_up_and_100bp_down_tss.mc9nr.feather"
And the error message I get is this one:

The current default is now to use all cells to match the behavior of the R verision of SCENIC. The original settings can be retained by setting 'rho_mask_dropouts=True' in the modules_from_adjacencies function, or '--mask_dropouts' from the CLI. Dropout masking is currently set to [False].
