How to plot the graphs (.dat) after using membplugin

[Natesh]

Hello all,
I would like to view again the thickness map (.dat format) that was generated after runnng calculations in membplugin. I am not able to find any option to load the data again and plot the same in membplugin. Kindly guide me on this.
Best regards,
Natesh

Dear Natesh,

The plot shown by thickness map is computed from values stored in memory and the software currently has no option to regenerate the plot from the .dat file. We will consider adding this option in a future release.

However, you can use a software package like R or python matplotlib to generate the contour map from the .dat file, or visualize the generated DX file in VMD.

For visualizing a DX in VMD you can follow this steps:

1. Open VMD and load as a new molecule your DX file at File --> New Molecule ...
2. Create or modify a representation in Graphics --> Representations ...
3. Set Coloring Method as "Volume", Drawing Method as "VolumeSlice", and the Slice axis as "Z".
4. Open "Color Scale Bar" tool in Extensions --> Visualitzation --> Color Scale Bar.
5. Set the option Autoscale to "on", set "Use Molecule" to the molecule where DX file was loaded, and set "Use Representation" to the VolumSlice representation created on steps 2 and 3.
6. Press "Draw Color Scale Bar". A color scale bar will appear as a legend for the colors shown in the VolumSlice representation.
7. Set the color scale used on Graphics --> Colors ... at "Color Scale" tab (e.g. RGB).
8. For having an idea of the X and Y axis values you can use the Extensions --> Visualitzation --> Ruler, press "Switch to Orthographic Mode", and select "grid" instead of "tape".
9. Reset the view by pressing '=' key or in Display --> Reset view.
10. Press 'S' key and scale the representation by clicking and holding mouse left button and moving the mouse from left to right.
