Loads fine for me. A couple of hints when it comes to visualisation (which I suspect is where your problem lies):

- the standard visualisation of a newly-loaded map is "points" and the default colour is white. If you've set your background colour to white, your map will be invisible until you change the representation.

- this particular map opens up at its maximum isovalue, where nothing is visible. Reduce the value to a suitable level.

In short, just play around with the different options in the Graphical Representations window, and you should find it.

Subject: vmd-l: VMD cannot display electron density map

Dear all,

I find VMD cannot load .map format density map file. In order to do mdff, I convert my target .situs format density map file using map2map command in the Situs program suite. However, when I load the generated .situs format file into VMD, it shows only the box and no isosurf electron density is shown. Is it caused by certain bugs in VMD or problems in the electron density map itself

   The .map and .situs format files is available with the following link

Best regards.
