Thanks.

This is my input file.
I'm doing that also.

#trajin md5.trj.gz
#trajin md6.trj.gz
#trajin md7.trj.gz 1 500 1
vector v1 .12 @13
#vector v2 :4-37.P corrplane order 2
analyze timecorr vec1 v1 tcorr 1500 dplr norm out cn.cf
#analyze timecorr vec1 v2 tcorr 1500 out memb.cf
#analyze timecorr vec1 v1 vec2 v2 tcorr 1500 drct dplr norm out cn-memb.cf
go
=============================

Nothing works.

The warning message is

WARNING in ptraj(), analyze timecorr: wrong vector type given, ignoring command


As I have mentioned, vector problem can be solved by removing "corr",
but "analyze timecorr" never works.
