Its not a center command problem, rather your trajectory file
C-C1-md2.mdcrd has a problem ..
Can you load the trajectory in vmd?

Obviously your trajectory file is corrupted ... I guess you should check
if you can load this file into a visualization program (vmd for
instance) and then check whether you have only 1 or several frames
corrupted or the entire file has a problem . If only several frames are
corrupted than you should use ptraj to remove those frames (see trajin,
trajout commands) and go on to the next step with the new trajectory ...

If the entire file is corrupt ... then I am afraid you should track the
problem somewhere in your MD run ...
