Hello,

Thank you for your suggestions. I have already tried run trjconv but, as 
trajectory is heavy and server is full, out of memory error appears and 
analysis tool crash.

Best,
Rita.

Hello Rita,

I think the answer is trjconv. Try to convert it to xtc, reduce the number of 
frames (with dt or skip), or reduce the components on the trajectory. If you 
don't need solvent for the calculations you can create a trajectory without it. 
Removing the solvent and convert it to xtc should have a great impact in file 
size.
