How to create a 3D-surface plot from potential energy surface data from Gaussview?
Afficher commentaires plus anciens
How do I create a 3D-surface plot from a Gaussview file where I generated a potential energy surface via scan of a molecule?
This is how it looks like in Gaussview:

And this is the data file:
# 2-Coordinate Scan of Total Energy
# Title = Gaussian Scan Grid
# X-axis = Scan Coordinate 1 = SC1
# Y-axis = Scan Coordinate 2 = SC2
# Z-axis = Energy = E
#
# List Format
# Node X Y Z

I started to read the file and separated x, y, z like this:
Scanfile = 'scan_PES.txt';
Import_Scan = readmatrix(Scanfile);
x_scan = Import_Scan(1:144,3);
y_scan = Import_Scan(1:144,4);
z_scan = Import_Scan(1:144,5);
But when trying to plot, I get some errors:
s=surf(x_scan,y_scan,z_scan);
Seems like I need something more. Does anybody has some suggestions?
