I am trying to analyze circular RNA. I have used STAR for alignment and DCC for detection. after this, I am trying to run FUCHS using the following parameters:

FUCHS -D /RNA/rna_anal/circrna/DCC/CircRNACount \ -J /RNA/rna_anal/circrna/sortedbam_paired/mkAChimeric.out.junction \ -F /RNA/rna_anal/circrna/sortedBam_mate1/mkA.1Chimeric.out.junction \ -R /RNA/rna_anal/circrna/sortedbam_mate2/mkA.2Chimeric.out.junction.fixed \ -B /RNA/rna_anal/circrna/mate1_2_mergedbam/mkA.merged.bam \ -A /RNA/rna_anal/circrna/bed.BED \ -r 2 \ -q 2 \ -p ensembl -e 2 \ -T ~/tmp \ -P 7 \ -N mkA \

But I found the following error.

File "/home/mamu/.local/lib/python2.7/site-packages/FUCHS-0.2.0-py2.7.egg/FUCHS/FUCHS.py", line 179, in main

`output_file = open('%s/%s.logfile.%s' % (outfolder, sample, dt.replace(' ', '_')), 'w')`

IOError: [Errno 22] invalid mode ('w') or filename: '/RNA/rna_anal/circrna/FUCHS//mkA.logfile.2020-05-07_20:28:35.094516'

I have tried to find any solution on the FUCHS manual here and on google, unfortunately, I wasn't able to get any solution so far. Could you help me in solving this error, please? Thank you in advance for your help.
