I have not tried the following with attempting to resurrect diffraction data from old published papers or reports but such an attempt could be interesting(?): The following refers to a list of programs that can Convert a hard-copy graph or plot into data. Possibly quite handy for comparing hard-copy Rietveld/diffraction results of the past with the present. http://www.ccp14.ac.uk/solution/hardcopy2data.html -------------- This presently includes: Datathief for Mac (freeware) http://www.nikhefk.nikhef.nl/~keeshu/keeshu.html (can handle log scales and "data thieving" of curves (diffraction data?), lines of best fit). Quicktrace for Mac (freeware) http://servermac.geologie.uni-frankfurt.de/QuickTrace.html (looks a lot more powerful than datathief in that it can handle a wider variety of graph types - distorted images as well - ternary, polar, etc. Written by the same author of the free MacDiff Powder diffraction software - Rainer Petschick). TechDig for Win95/Win3.11 (shareware) http://www.xnet.com/~ronjones/index.html ============== Other programs to add to the list are welcome as well as some "rumoured" programs that can handle hard-copy stereo structure diagrams and get the structure co-ordinates back? ============= Lachlan. -- Lachlan M.
