Re: [AMBER] combining crashed trajectories

Hi,

One thing you might consider doing is adding a 'check' command with
the 'skipbadframes' option to skip over frames with corrupted
coordinates. In my experience when a NetCDF trajectory frame is
corrupted it tends to be an 'all or nothing' situation, so checking
the first few atoms of the system (for speed) usually suffices,
something like:

trajin <trajectory>
check .1-10 skipbadframes reportfile report.dat
trajout nobadframes.nc

Then check 'report.dat' for which frames had issues. I like doing this
as a first pass because if you have corrupted frames, things like
'autoimage' will fail anway. Hope this helps,

-Dan
