Hello everybody. I'm trying to extract some features from my protein sequence dataset. I'm using iFeature toolkit. When I run iFeature on my system, it gives me a non-sense output. It provides an output file with a lot of zeros. It seems like it doesn't calculate anything. By the way, I'm working on a Linux environment and using Python 2.7 to run iFeature. The command which I use is python iFeature.py --file ../Mesophiles/cdhit_output.70 --type DPC --out ../DPC/Mesophiles/DPC_70_meso.txt. II'll be grateful if anybody helps with this problem.
