Hi, There is a chore that needs to be done that would have an impact far beyond Ifeffit and friends, but which I don't have time to devote to right now. Consequently, I am looking for a volunteer to take this on. OpenBabel (http://openbabel.sourceforge.net/wiki/Main_Page) is a very cool molecular and chemistry package. It is a library which allows programs to easily convert between different file formats for describing molecules and clusters of atoms -- a chore in what you might call chemoinformatics. As an example, a program using OpenBabel can import a file from the Protein Data bank and export an input cartesian file for Gaussian. OpenBabel supports 70+ file formats for this conversion process (http://openbabel.sourceforge.net/wiki/Category:Formats). One format OpenBabel does not support is feff.inp. I trust it is not hard to imagine how useful it would be to be able to easily convert cartesian data in some other format into valid input to Feff. Any program using OpenBabel (http://openbabel.sourceforge.net/wiki/Related_Projects) would immediately be able to generate feff.inp files. And because there is a perl wrapper for OpenBabel, Artemis would be able to import virtually any kind of cartesian data. Super cool! OpenBabel is written in C++ and comes with very clear instructions (http://openbabel.sourceforge.net/wiki/HowTo:Add_A_New_File_Format) on how to add file formats. I would like someone to volunteer to write, test, and document format code for feff.inp files. I am happy to give advice in the design phase and to help with testing. I think this is a highly rewarding project in the sense that the ratio between the impact on the Feff-using community and the time required for taking on this chore will be quite high.
