I reported that already weeks ago. For some unknown reason the number of frames is now stored in the field 5-ZEROS, instead of NSET.


Interestingly VMD doesn’t care.

Betreff: namd-l: NAMD2.11 DCD HEADER PROBLEM


Dear all,


moving from NAMD2.10 to NAMD2.11 I am no more able to read the number of frames from the header of the dcd file, what I get now is a 0 value.

This happens reading the dcd header with an in house fortran code but also with the dcd-header-manipulation code downloaded from:



All the remaining info in the header are ok, just the number of frames is corrupted.


Thanks in advance,
