Hi, I am just wondering if there is any way that I can have two or more volume viewer windows open at the same time. I am comparing two density maps and to be able to change the threshold and color for both maps, without having to go back and forth in the same window, would be much easier and useful. Also, I recently fitted a pdb crystal structure into a density map but was not able to save it with relation to the density map (the feature which was available in previous releases). However, if I have multiple pdb files open then I can save the pdb file of my interest with respect to the map. Is there anyway to save a fitted pdb file with respect to a density map without opening other pdb files? Thank you, Batsal. -------------------------------------------------- Batsal Devkota Graduate Student, School of Biology GeorgiaInstitute ofTechnology Atlanta, GA 30332-0400
