Hello:

   I am going to extract Desmond MD frames by CATDCD into a single PDB
file, here is my command:

catdcd -o mytest.pdb -otype pdb -i MD_trj/clickme.dtr -first 1 -last
2000 -s MD-out.cms

but it claimed:
-----------log-------------
CatDCD 4.0
Reading indices from file 'clickme.dtr'
Error: no indices found in file.

Would you please give some advices?

thank you very much
