Thanks, Nuno,

Becuase the file is too big, so gmxcheck does not work also.

Thanks, I understand this. but when I split the big *.trr file using:

split -b size of 501frame -b size of 500frame*6  *.trr

it does not work, it seems that split can only split the big file into the
small chunk of same size, what is your way to split the big file into small
chunks? Please do not tell me that split the big file into 3501 files, then
combine them together. I thinks that there should have some ways to split
into several limited files such as 2ns interval, 1ns interval etc.


Thanks,
