[Chimera-users] saving maps generated with molmap - origin?

Hello, I'm wondering why when I generate a density map from a pdb structure (using the molmap command) and then save it, once I reopen it it seems to have shifted with respect to the structure. I'm noticing that before saving it, the generated map has a certain origin (shown in the Coordinates pane in the Volume Viewer), and then when I reopen it the origin appears as 0 0 0. If I copy the origin shown initially and then paste it into the origin of the opened file, this shifts the map to the correct position, but why isn't the right origin saved with the file? I'm using alpha version 1 build 2509 2008/05/01, platform win32 Many thanks, Greg
