@holmrenser Does it help if you rename test.bed to test.gff and/or re-arrange the columns so that the name of the gene is second?

@brkldj It did, took me a while to figure it out. The readme says input files should be in bed format, which has the name of the feature as 4th column (see https://genome.ucsc.edu/FAQ/FAQformat.html#format1).
I'll submit a PR to suggest a fix for the readme.
Thanks that just reallllly hurt my head for a good 45 minutes now...
Hello,
I was having the same issue and none of the above solutions worked for me. My files are in the same format as @farhan-lab 's.
I finally realized that (surprise, surprise) my command was not quite right. Say my files are named dir.blast
and dir.gff
. Initially I was running MCScanX path/to/dir
when I needed to specify the prefix of the .blast and .gff files as well: MCScanX path/to/dir/dir
.
I both hope this works for someone and also apologize if it does because now I feel stupid :)
Hi,
Did you ever get this working @farhan-lab ? I have the same issue .. inputs seems to be correct (after a lot of confusion), but still MCscanX isnt running ..
hi. Yes It worked for me. I was giving blast output of my target genes instead it should be the blast of protein and gff of the whole genome. Let me know if you want to learn more

Hey @holmrenser and @siv-n,
It looks like I am having the same issue as you two did. In particular I am getting the message as @holmrenser that all matches have been discarded. Was only thing you did to get it to work changing the order of the .gff?
My .gff is already as described with gene coming in second place.
I can get the program to run on the test data, but not this data, which is the same in format as far as I have been able to discern, unfortunately.
Any pointers would be appreciated.

It is important to note that although the github says for the gff file that it should be 'ch#\tstart\tstop\tgeneID', this is incorrect. The geneID needs to be the second column.
Also, the geneID's in the gff file need to EXACTLY match the geneID's in the blast algorithm. Any difference will result in no matches.
I had this same issue. What solved mine (after changing the order of the geneID) was making sure the gff file was named '.gff' not '.gff3'
Hope this saves a headache.
Thanks @brysonab.
Hi,
I am trying to compare two snake genomes for identifying collinear genes but currently having some issues with MCScanX. Even I have generated the gff and blast files having exact same genes ids in both files, but the output collinearity file is empty.
