Trajectory export

Dear all,

I performed MD simulation using Forcite for periodic system (COF with over 100 000 atoms in supercell if it play any role).
Calculation ends up successful, i found and download .trj file (5Gb binary) and generated .msi file (is not generated automatically). Thus i manage to download in Material studio my trajectory and can jump between frames using animation option.
Now i would like to perform analysis of obtained trajectory (i am looking for centers of masses of different fragments of a system and so on). I did not found proper tool in MS so i decided to export trajecory in any human-readable format. However whatever i try i can export only one frame per time. For 1000 frame trajectory that sounds quite exhausting, especially taking into account that export of a 100000atom-frame to for example xsd takes few minutes.

Could anyone provide any suggestion to this case?

Thanks a lot in advance
