Error when concatenating final sheet (local variable 'r1_dt' referenced before assignment)

[msaland]

Hello,

I'm currently running the SCAPE package on some single-cell GRCm39 data, and it's running well up until the last step where it's concatenating the final sheet, where it gives this error:

2024-07-02 10:45:19.226 | INFO | cli.apamix:apamix:197 - Concating your final sheet
multiprocessing.pool.RemoteTraceback:

The above exception was the direct cause of the following exception:

I've previously run it on some single cell Grch38 human data without issue, so I'm surprised to see this error now.

Thanks,
Mike

Hello,

I didn't notice your command and am unsure why it didn't work. Please try using the latest version of SCAPE from https://github.com/chengl7-lab/scape.

I have been trying to use the newer version, but unfortunately I've been having issues (same one as chengl7-lab/scape#2).

As for the command I ran:

python /workspace/lab/hanlab/software/scape/main.py apamix --bed GRCm39_utr.bed --bam .bam --cb .tsv --out <out_folder> --tag CB,UR --cores 24
