[gmx-users] Specified frame doesn't exist or file not seekable

[sudheer babu]

Hi all,
       I am having 7.25ns trajectory file , I am trying to pick up  6250ps
to 7250 ps  trajectory file from whole trajectory by using trjconv,
Command line is
    *trjconv  -f  7.25ns.xtc  -s  pr.tpr  -o 6.25_7.25_out.trr  -b  6250
-e  7250
     selected  " system " for getting output
 it showed the following error
-----------------------------------------------------------------
Program trjconv, VERSION 3.3.1
Source code file: trxio.c, line: 635

Fatal error:
Specified frame doesn't exist or file not seekable
-----------------------------------------------------------------------

 I have found few discussions in gmx-archives regarding this problem and due
to BUG in source code its showing error.
 How can i solve the problem ?
Thanks alot in advance .
