Hello there, I am writing to seek clarification regarding the following: I use GROMACS version 5.1.2 and Grace (xmgrace) version 5.1.25
I ran a molecular dynamics simulation for 1 microsecond (~ 1055 ns). I used xmgrace to plot a carbon-alpha RMSD plot and I noticed that the x-axis [Time (picoseconds)] is suggestive of the fact that the total simulation time was 1e+09 picoseconds (1000 microseconds). Furthermore, invocation of gmx rms did not involve the option -tu, therefore it was set to default (i.e., picoseconds). I discarded the initial portion to equilibration (250 ns). The question I have is if I considered the values in femtoseconds then the RMSD plot as it appears makes absolute sense, however the x-axis is clearly set in picoseconds. I thank you for your kind assistance.
