[gmx-users] version 3.3.1 .tpr file with version 3.2 g_order

[Michael]

        The g_order tool in gromacs 3.3.1 is broken.   I know that there 
is a patch available that would fix it, but a colleague advised me that 
recompiling g_order would not be quick and easy.  I therefore thought 
that I might use g_order from gromacs 3.2, but it complains of a version 
3.3.1 run input file with the version 3.2 g_order program.  The error 
message is:

Fatal error: reading tpx file (./topol.2.tpr) version 40 with version 31 
program

Is there any way that results from a simulation in gromacs 3.3.1 can be 
analyzed with an older version tool?  For example, would it work to run 
the version 3.3.1 .tpr file through the version 3.2 tpbconv program to 
get a new .tpr file, or would it yield the same error? 

Thanks for any suggestions
