Hi there,
I don't think zUMIs will work in your use case? If you just have plain cDNA to map, you could directly apply STAR! zUMIs becomes useful if you are handling cell barcodes and optionally UMIs.
Best, Christoph
Do you have any advice for determining based on a sample if there are barcodes or UMIs to map? I was under the impression this sample did have some, and when I add BC(1-8)
to the base_definition
I get the following under the Filtering step:
Wed Dec 21 15:47:32 UTC 2022
[1] "17 barcodes detected."
[1] "22001 reads were assigned to barcodes that do not correspond to intact cells."
[1] "Found 35 daughter barcodes that can be binned into 16 parent barcodes."
[1] "Binned barcodes correspond to 6949 reads."
However, I still have the same sjdbOverhang
errors.
Difficult to guess this, but you could try to look at FASTQC and check if something stands out there. For the sjdbOverhang, did you create the STAR index without GTF file as recommended:
https://github.com/sdparekh/zUMIs/wiki/Usage#preparing-star-index-for-mapping
I re-indexed without the GTF and am now getting this error when mapping:

It's not clear to me what file STAR failed to open.
I'm pretty sure it doesn't agree to the SRA-style readIDs from the input bam file, give this a shot: https://github.com/sdparekh/zUMIs/wiki/Reprocessing-of-public-data
Describe the bug When trying to run zUMIs I receive the following error:
EXITING because of fatal PARAMETERS error: present --sjdbOverhang=15 is not equal to the value at the genome generation step =100
To Reproduce YAML:
Output:
Desktop (please complete the following information):
Additional context The warning says that STAR version 2.7.1a was used for indexing, but this is not the case. 2.7.3a was built from source and used. I suspect that STAR does not properly write the version to the file that zUMIs is checking.
