Dear users I am going to analysis H-bond and Hbond occupancy using READHBMAP,I downloaded and extracted READHBMAP.TAR.GZ but after typing: ./readHBmap.py -hbm hbmap.xpm -hbn hbond.ndx -f md6.gro -o occupancy.xvg -op pairs.dat ,the message "permission denied" will appear. I would appreciate any suggestions. Best regards
