Michael, thank you very much for the DX files. That was just what I needed. Frieda, by the time you read this I will have uploaded a new 11.1.18 version of Jmol that reads these DX files in the form:
ISOSURFACE sasurface map "1dry.dx" Then from the application write isosurface "1dry.jvxl" saves the Jvxl file. To read that back in, just: load 1dry.pdb isosurface 1dry.jvxl That does it. Jmol can now map this APBS data onto any molecular surface. I'm happy to report that the resultant JVXL surface WITH the mapped colors comes in at 64K (this for 1dry.pdb). That's the expected 300:1 compression, considering that only 2/3 of the JVXL file is color data (40K). Basically that means we see a compression from 12900 KB to 40 KB. I can live with that! Michael, if you don't have a clue what I'm talking about, check out http://www.stolaf.edu/academics/chemapps/jmol/docs/misc/JVXL-format.pdf Basically what I have created is a very compact file format that Jmol can read and write (in command-line batch mode if desired, by the way). These "Jmol Voxel" files incorporate ONE full surface or planar slice with color mapping. The savings is due to the fact that we can't arbitrarily map the resultant data onto any data set. The mapping is done -- this is now effectively a 2-D selection from the 3D data -- 2D in the sense that all surfaces, no matter how curved, are still two dimensional, not three. So we see this incredible compression. Frieda, I'm compiling now, and Nico will be updating the SourceForge site sometime Wednesday, I expect.
