it looks like that "undocked..." line should not be there, is it a title?
concerning the # of RMSD values, I don't know what could be
wrong, I always get the same number that ptraj says it is writing.
this is 2398 values - do you get that? you say it is 1860ps but
I don't know how many frames should be in the files.
look at the ptraj output for each of the files, it will tell you how
many frames it found in the trajectory. check that against
what you think should be there and narrow it down to
perhaps 1 file that doesn't match. you have so many files
in this run that it is harder to debug.
