hi ekta,
please check again. have a look at this:
[akohlmey_at_athanor ~]$ which catdcd
/usr/bin/catdcd
[akohlmey_at_athanor download]$ catdcd -o tmp.dcd -xyz try.xyz
CatDCD 4.0
Opening file 'tmp.dcd' for writing.
Opened file 'try.xyz' for reading.
Read 21 frames from file try.xyz, wrote 21.
Total frames: 21
Frames written: 21
CatDCD exited normally.
hmmmm... seems to work ok, right? ;-)
cheers,
axel.
