There is a new version (V1.3) of FOUE available at: http://www.ccp14.ac.uk/ccp/web-mirrors/scott-belmonte-software/ FOUE extracts the Fourier density data in GSAS Fourier map files and converts it into a variety of formats including an ASCII dump. This update fixes some problems reading EXP files. The new GSAS manual giving a fuller description of the Fourier map format; with this information I was able to fix a problem reading Fourier map files that had more tham 8191 densities per section. A bug found in the interpolation routine used to create Marching Cubes and Project XD formats has been fixed. Also available: PATE, which extracts obverved, calculated and difference and patterns and phase tick marks from a GSAS refinement and outputs ASCII files suitable for input into a plotting package.
