There was/is a bug in handling compressed Amber trajectories in that the number of frames was being estimated based on the compressed file size rather than the uncompressed size. Therefore it was only using a fraction of the available frames -- and therefore specifying multiple compressed coordinate files would seem like it was using only the first one since the sum of the under-estimated frame numbers might add up to approximately the correct number for the first file alone. The fix will be in tomorrow's daily build. --Eric On Jan 4, 2008, at 7:06 AM, Francesco Pietra wrote:

I was unable to input more that one mdcrd file to MD Movie (to get a single pdb file for EnsembleCluster). I tried by either giving the files one to one, or with the following prod.meta:

amber my.prmtop prod1.mdcrd.gz prod2.mdcrd.gz prod3.mdcrd.gz

Always, I got prod1 trajectories alone.

I used compressed coordinate files also when fed one to one. I did not try with non compressed files.

Thanks
