use.i've read gromacs manual 3.3 but i'm in need of any other new analysis
are included in version 3.3 or not.so where can i getthe information on
availability of more analysis in GROMACS 3.3 version comapred to older
thanks sir.i'm in hurry.Plz anyone help me.
hello, you can use g_sham program (new one in 3.3)to calculate free energy
distribution and draw the picture.
first, you should prepare a xvg file with three columns. the first is frame
time, the second and third are the parameters you want to calculate, for
example like this:
Time RMSD dist
0 1.2 0.8
1 1.3 1.1
2 0.5 0.9
. . .
. . .
and then, use the following command:
g_sham -f *.xvg -ls
you can get the pic, and with -ngrid you can get the high resolution pics.
