[gmx-users] g_dist error?

[Marc Charendoff]

Hello,

      I am in the middle of analyzing the distance between two atoms of a MD trajectory when I ran into the following error thus stopping at 3 ns of a 4 ns trajectory. What could be the issue?

Select a group: 18
Selected 18: 'a_1899'
Select a group: 19
Selected 19: 'a_2498'
trn version: GMX_trn_file (double precision)
Reading frame       0 time    0.000   
Back Off! I just backed up C4AHL_Y194.xvg to ./#C4AHL_Y194.xvg.1#
Reading frame    3000 time 3000.000   
-------------------------------------------------------
Program g_dist, VERSION 3.3.4
Source code file: trnio.c, line: 66

File input/output error:
Can not determine precision of trn file
-------------------------------------------------------

Thanks, Marc
