Perkin Elmer GC Method File Format

[smsanalytical]

I'm attempting to index all our Perkin Elmer Turbomass 5.4.2 projects on the 32-bit Windows XP hard drive to make a report of all work done that I can run each month. So far I've managed to parse the project INI file as well as the mass spec conditions (start and end scan etc) in the EXP file format. What I've yet to achieve is parsing the GC's MTH file format as it appears to be stored in an odd binary format. I've been trying various hex editors to understand the content but have failed so far. What I want from it is the gc run conditions (start temp, end temp, ramps etc). Does anyone have information on how this MTH file is formatted ? I'm happy to write some C code to parse and should say that this is purely for my own benefit. I guess one of the PE registered DLLs might have a function I could call if I knew which.

Sounds like a fun challenge!
I don't think there are many on these boards with the level of programming/file structure/computer science expertise that would be needed to answer your question. Perhaps a site oriented in that direction might actually be more useful to you -- stack exchange or similar.
Good luck figuring it out, and if you do solve your problem, we'd (at least I'd) love to hear about it!

Yeah, it is. We at OpenChrom have some experience in decoding formats. Hence, please send me a short notice with the attached file. I could then have a look at it.

Hi Philip, thanks for the offer of help. I'll send you a sample file. Will do a follow-up post here if we get any further with this one.
