Problems when exploiting NAMD trajectories with CHARMM can arise from
1) PSF compatibility issues (NAMD works with X-PLOR PSF format), 2)
slight differences in the DCD format (in the header part), 3)
endianness problems, etc.
To solve 1) you have to generate the PSF at the beginning of your
project with the CHARMM program and write it in both CHARMM and XPLOR
versions. The catdcd and flipdcd programs can help you solve 2) and 3).
Have a look at these threads on the CHARMM forum:
