Dear all gromacs users
I am creating free energy landscape using g_sham but my axis are not
getting labelled. I have searched the archive and found that using xmin and
xmax options we can label them.
I have first created my 2D projection xvg file using
g_anaeig -f *.xtc -s *.tpr -first 1 -last 2 -2d *.xvg -v *.trr
and then found min and max values for both the vectors,
say for vector1 min:-2.25 and max:1.83
and for vector2 min:-1.60 and max: 2.22
and then I have used:
g_sham -f *.xvg -ls *.xpm -notime -xmin -2.25 -1.60 0 -xmax 1.83 2.22 0
and then converted *.xpm to *.eps using
xpm2ps -f *.xpm -o *.eps -rainbow blue
This way I got eps file with only one axis(x axis) labelled and following
line appeared:
Auto tick spacing failed for Y-axis, guessing 1.19375
I would like to ask is this way of labelling the axis correct? If yes, why
didn't y axis get labelled and how to solve the problem?
xpm2ps has very limited ability to label axis intelligently. If your x- and
y-axes are not easily divisible, then it fails (hence what it tells you above).
You have set minima and maxima that are not easily divisible by one another,
so tick spacing will not work nicely. Try ±2.5 for your data range in g_sham.
