Provide background peaks file as .bed instead of FASTA?

[apposada]

Hello,

I am writing an issue of 'other' type as I am not sure where to ask. I am trying to run gimme motifs with a custom, non-genomepy genome and I am getting the following error:

(gimme_venv) alberto@nostromo:/mnt/sda/alberto/projects/ananse_smed/outputs/gimme$ gimme motifs -b 202110XX_peaks_goodformat.bed -g /mnt/sda/alberto/DATA/dynamic/genomes/Smed/Guo/Smed.fasta /mnt/sda/alberto/projects/ananse_smed/outputs/wgcna/20220812_wgcna_smed_black_assocpeaks.bed  outdir

OSError: Not a valid FASTA file

I am unable to detect any problem with the FASTA file of the genome:

Correct me if I am wrong, but I understand the error refers to trying to pass the background peaks as a .bed file. Is it possible to do this, or must the background peak file be in .fasta format? I could not find any related info in the documentation.

Thanks in advance,

Alberto

Hi @apposada, this is something that should work. However, I think this is a bug that was introduced at the time I simplified the gimme motifs command-line. At a first look I could not find how to fix this, so this will need some more detailed bug hunting. Will get back to you!
