I didn't have a scanner handy, so the listing below is a direct copy from an old usenet post. There's not much more useful information than the listing below though. I managed to salvage a copy from the trash many years ago, so I can scan the relevant pages if you need it. It was originally listed in an appendix of the HP 59970 MS Chemstation Handbook which is long out of print. It hasn't changed since the days of the Pascal Chemstation (although I could be stand corrected). ms file format you're after, see below (sorry to you non-programmers!). Good freebie software adds value to instruments make life difficult for freebie programers, and you are alienating customers. If you don't publish your file-format, and someone decodes it and writes freebie software, then when it all goes pear-shaped because they were ignorant of something you later rely on, YOU will share the blame with them in the eyes of your (angry) customers. If any instrument-manufacturer ever reads this, let them beware. And when you come across some piece of data that always has one of several values, you never know whether you've seen the entire list of values it can have, and what the other values might mean, and how this meaning alters the interpretation of the data whose meaning you think you know.It means you're always skating on thin ice, and have no guarantee that you're interpreting the data correctly. The hideous worry is that if you do it by inspection, there's always some byte somewhere whose purpose remains unclear you never know exactly what options the original programmer had in mind. Incidentally, congratulations to eselmeister for producing some free software to look at a wide range of different MS raw file formats.īUT, I have slight concerns, though, about his comment on decoding file formats. The MS export thing in 32-bit didn't work properly for several versions (from the file-size I suspect it exported the TIC only, and not full MS data). If it's stupidly small, find someone with a more up-to-date version of Chemstation. If you run into problems with the exported file, check it's big. There are several flavours of Chemstation file, depending on what version of the software you have (Chemstation's 16-bit version has a totally different file-format to the 32-bit version, but Agilent have hidden this seamlessly such that you won't notice unless you try to open 32-bit on a 16-bit Chemstation). I would really, really recommend you find someone with Chemstation and ask them to copy your data from a disk and export it in.
