I've been using Kissplice pipeline lately to perform personnal RNASeq analysis. As I used the pipeline described in the official Kissplice documentation, I've come across an error.

With the following command line:

kissplice2refgenome-1.0.0/kissplice2refgenome -a genomeDir/gencode.v24.chr_patch_hapl_scaff.annotation.gtf --pairedEnd True kiss_emt/star_coherents_type_1_Aligned.out.sam

I get the following output:

Run starts...
Reading annotations file...
Traceback (most recent call last):
  File "workdir/kissplice2refgenome-1.0.0/kissplice2refgenome", line 140, in <module>
  File "workdir/kissplice2refgenome-1.0.0/kissplice2refgenome", line 109, in main
  File "/workdir/kissplice2refgenome-1.0.0/kissplice2refgenomelib/", line 22, in readAnnotationFile
  File "workdir/kissplice2refgenome-1.0.0/kissplice2refgenomelib/", line 28, in getInfoAnnotationFile
    gettingAttributes=event[8].split(" ")

I just grepped out the headers in the GTF file to get rid of the error, as follows:

kissplice2refgenome-1.0.0/kissplice2refgenome -a <(cat genomeDir/gencode.v24.chr_patch_hapl_scaff.annotation.gtf | grep -vP "^#") --pairedEnd True kiss_emt/star_coherents_type_1_Aligned.out.sam

I was wondering if this was a known issue ? I just downloaded the GTF file from gencode, and did not perform any modification (aside from gunzip uncompression).

Dear Thibault,

Sorry for answering so late to this post, but yes this issue was corrected a long time ago now. Thanks for reporting it. The current version of k2rg is now 1.2.2 and you are welcome to try it.
