Hi all, A pdf version of the new GSAS Manual has been put on the distribution site ftp://ftp.lanl.gov/public/gsas in the directory manual. The technical descriptions are fully up-to-date for all functions used in GSAS. The file format descriptions particularly for raw powder data have been completely redone and there is now a new exercise for lab x-ray powder diffraction data. One should refer to this version of the Manual for any work using GSAS. A.C. Larson and R.B. Von Dreele, "General Structure Analysis System (GSAS)", Los Alamos National Laboratory Report LAUR 86-748 (2000). Please let me know of any errors or omissions as I plan to fix any that are found and reissue the manual as needed. Bob Von Dreele
