The source code for versions of RasMol up through 2.6 is in the public domain. See: http://www.umass.edu/microbio/rasmol/faq_ras.htm#pubdom http://www.umass.edu/microbio/rasmol/srccode.htm In addition, the Jmol project has explicit permission from Roger A Sayle to make use of RasMol source code up through 2.6.* The OpenRasMol project http://www.openrasmol.org, starts with 2.7.* annd has different licensing restrictions that are not currently compatible with Gnu licensing terms.

Certainly, please feel free to read, re-use, re-code, whatever, any of the source code contained in RasMol versions up to and including v2.6.x. All of these release of RasMol were distributed as "public domain", i.e. free from any intellectual property rights claims whatsoever. Indeed this is the legal reason why the source code could become part of MDL's Chime and MSI's WebLab viewer products. > Nevertheless, I would feel more comfortable if you gave the Jmol > project explicit permission to use your source code as a reference.
