Hopefully you have modified the decane.itp that you found in the /share/top subdirectory; it is for use with ffgmx, which no one should probably be using anyway.

ERROR 0 [file "vegfr2.top", line 37]:

Program grompp, VERSION 3.3.3
Source code file: grompp.c, line: 1205

Fatal error:
There were 764 errors in input file(s)

You have a crippled topology. Either the format is wrong, your #include statements are wrong, or your [ molecules ] section is out of order...or maybe even more possibilities. With this many errors, it is hard to diagnose without actually seeing the topology.

I would appreciate some help on the matter.
Thank you in advance
