For some reason, ptraj doesn't agree:

Make sure you have read permission for the fimd.mdcrd. Try the command "head
fimd.mdcrd" to see if you can indeed read it, and that it looks like other
trajectory files that "work".

Also, leave out the spaces in the atom selection mask, and the final comma
(after O3'):

rms first mass out m22g_calc_backbone.rms ".P,O5',C5',C4',C3',O3'" time 0.2.
