Dear Jin, The Volume Viewer tool in Chimera can be used to view all kinds of 3D numerical data sets. The data does not need to be molecular. However, a limiting factor is whether the format of the data is understood by Chimera. Here is a list of the formats understood by our last release: http://www.cgl.ucsf.edu/chimera/1.2184/docs/ContributedSoftware/ volumeviewer/volumeviewer.html#formats Another release will be coming out soon, and it can also read Purdue image format, Situs map files, and Gaussian cube grid files. The CT data format may be different from all of these; if so, to use Chimera, it would be necessary to add the format description using Python code: http://www.cgl.ucsf.edu/chimera/1.2184/docs/ContributedSoftware/ volumeviewer/volumeviewer.html#newformats I hope this helps, Elaine ----- Elaine C.

Dear Sr/Ms,

I wonder if chimera molecular modeling system can be used beyond molecular level. we try to use chimera to create 3D images on mouse colon crossection images(dataset) we collected from SKYSCAN Micro- CT 1076 . Do you think it will work? Looking forward to your opinion. Thanks in advance,

Jin
