[gmx-users] Character issues

[Kelsy Yuan]

Hi Mark,

Thanks for your quick reply. I tried to use Gromacs 5.0.6 to grompp, it did
give me a little bit more information about the error, without mentioning
"20s". However, I cannot find the exact position since I don't have that
line in my input file. There is not much information about it on the
website nor manual. I wonder is it possible to get some further
explanations? Thank you in advance.

-------------------------------------------------------
Program grompp, VERSION 5.0.6
Source code file:
/usr/local/src/gromacs-5.0.6/src/gromacs/utility/cstringutil.c, line: 112

Fatal error:
An input file contains a line longer than 4095 characters, while the buffer
passed to fgets2 has size 4095. The line starts with: '1     AL1     1
  UNL     A2'      ay1
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors

Sincerely,
Kelsy
