Hey all. I am doing a differential expression analysis and trying to use grep to find genes that are up-regulated and also those that are down-regulated by comparing the genes ortholog of different species of a bacteria to the Deseq2 result of each species. However, I think something is wrong with my grep command and I am getting an error. I would appreciate any help or explanation.
the command I am using to find the up-regulated gene (in terminal) is
grep -f up./Users/flynt/Desktop/Deseq2/3084DEortho.txt geneortholg./Users/flynt/Desktop/Deseq2/30_84_vs_all.txt > 3084DE.txt
I am a beginner in this field. Thanks in advance
