hi,
i am writing all the input commands i am doing:
>ptraj am15_wat.prmtop <<EOF
>trajin am15_rem.mdcrd
>strip : WAT
>trajout am15_nwat.mdcrd
EOF
it gave segmantation fault.
Now i calculated the no of indices of water molecules from the prmtop file and did it another way like
>ptraj am15_wat.prmtop <<EOF
>trajin am15_rem.mdcrd
>strip : 423-98707
>trajout am15_nwat.mdcrd
EOF
the command is working results :
PTRAJ: Processing input from "STDIN" ...
PTRAJ: trajin am15_rem.mdcrd.rep1
Checking coordinates: am15_rem.mdcrd.rep1
PTRAJ: strip :423-98708
Mask [:423-98708] represents 97110 atoms
PTRAJ: trajout am15_rem_nwat.mdcrd
PTRAJ: Successfully read the input file.
Coordinate processing will occur on 800 frames.
Summary of I/O and actions follows:
INPUT COORDINATE FILES
File (am15_rem.mdcrd.rep1) is an AMBER trajectory (with box info) with 800 sets
OUTPUT COORDINATE FILE

are using and not the actual input. This can waste our time if you introduce a typo or
extra spaces, etc. If you want help, show us EXACTLY what you used as
input and what you got for an error message. Don't re-type it, copy and paste it.

Try specifying the actual file names instead of *'s
