Hi Eric, Thanks for replying. I may be wrong, but what I understand from the online manual is that we have a higher precision in MD calculation (as in trr file). I am not sure if grompp recognizes a higher precision than 3 decimal places.
When I did editconf with a gro file with higher precision as an input, I got an output gro file with coordinates rounded to 3 decimal places. So I am a bit doubtful if it's the case with the grompp program. 2017-06-15 11:49 GMT+01:00 Eric Smoll <ericsm...@gmail.com>: > Hello Yu, > > Read this carefully. > > http://manual.gromacs.org/online/gro.html > > As far as I know, Gromacs will accept gro files with high precision if the > input file follows this format. > > Best, > Eric > > > On Jun 15, 2017, at 4:33 AM, Yu Ogawa <ayo...@gmail.com> wrote: > > > > Hello gmx users, > > Can we increase a precision of input structure file more than 3 decimal > > places? > > Thank you for your help! > > Yu > > -- > > Gromacs Users mailing list > > > > * Please search the archive at http://www.gromacs.org/ > Support/Mailing_Lists/GMX-Users_List before posting! > > > > * Can't post?
