[gmx-users] Question about DNA simulation

[Chris Neale]

I am not sure if you read my previous reply here:

To be more explicit... you made a spelling mistake. "-D" is a flag and 
"FLEXIBLE" is what you are defining. You put an "E" between the two. 
Remove it. If that doesn't fix the problem then you are going to need to 
be more specific about your problem.

Chris.
