Hi Bo,
it looks like the first error is occuring because either csh or namddat
isn't in the proper place. If you could, please try running
csh namddat
and let me know the results (no need to copy to namd-l). If it fails
please also send me the results of the command
which csh
The reason that namdplot-2 isn't working is simply that the newly
created file doesn't have execute permissions set. If you run
chmod u+x namdplot-2
and then try running namdplot-2 again, it should work.
Please let me know if things still don't work after trying this.
Best,
Peter
