OK I could not resist after a weekends action packed surveying. Learning to use software that crashed for me but held the promise of an instant transfer was less daunting than manually transferring 5 top files into therion. Your clarifications of the instructions must be OK cos I got the files to go where I expected first try (apart from a typo I made that copied the raw files into the wrong place - lucky I didn't blindly add those to my repository-seems to be a dangerous feature) Hope 1.2.3 produces accurate files Andrew, cos it looks like its progeny are going into my live project. The problems I was having with it not running therion and survex were due to the paths - my therion is on the D: drive - my oversight. Have attached the log file - seems to have a lot of debugging going on? And seems to indicate it has stopped mid process, although it did everything I expected. I still cannot use the map export pdf from the thconfig topparser produces - strange metapost type crash it seems so may be nothing to do with topparser. All my other projects OK. A feature request (from a cautious new user). I wouldn't mind the ability to create a backup dump like PocketTopo's 'export text' and 'export therion' and have them place in the 'raw' folder. Are you able to include a script to get PocketTopo to do that without user intervention? (I'm assuming coding topparser to imitate those is a lot of work and would involve a long testing period to be sure that faithful reproductions of the formats were being produced). Bruce
