Bob Thank you very much, that was very fast. I have checked my instrument, and I don't see that option in the control panel, but that isn't something I've had a desire to do yet so I've not looked into it heavily.

It is simple in that it assumes only one RawData subfile in the .brml file. It does rescale all points by the true count time/step vs the apparent ount time. This is a slight effect unless a variable count time data collection scheme is available from Bruker (I've no clue about that). NB: it will conda install xmltodict if it is absent from your python (it's not usually installed in GSAS-II python). It will read multiple .brml files if they are selected. PWDR entries are named according to the brml file name. It does not retrieve wavelength or environmental data at the present time.

At the moment it is written as a filter so I can convert a bunch of data at once.

I am happy to share it. The brml file is simply a zip file with an XML folder with all the information about the experiment. Carlo On Mon, Oct 17, 2022 at 1:18 PM Brown, Matthew via GSAS-II <[email protected]<mailto:[email protected]>> wrote: Salutations I hope I'm sending this to the right place. I was at the Canadian Powder Diffraction Workshop last week, and noticed that GSAS-II doesn't seem to support *.brml files, what my Bruker PXRD saves as by default. That format is just a zip file full of xml wearing a fancy hat, so it is quite easy to parse; the python unzip library opens it perfectly. I'm actually doing so for a project I'm working on.(1) If GSAS-II wanted to support *.brml files, I'd be glad to help: if someone gave me a list of what GSAS-II needs to extract from the file, I could work out where in the XML that is stored for you. I might even be able to write up the extractor if you told me what output formats you, but I'm not the world's greatest programmer(2) so I'm not sure you'd want me directly contributing code. 1. Since many of you know I'm very new to PXRD, don't worry, I'm not trying to do any actual calculations. I just got tired of looking up the settings I'd run every experiment at in EVA each time, and worried that I would make a typo and the user would report the wrong parameters in their paper, so I wrote up a little python tool that extracts those numbers into a format I can just copy and paste and send to the user. 2. My script doesn't even use an XML parser, I just brute force loop over RawData0.xml using stuff like "elif line.startswith('<TimePerStep>'):" Let me know if me documenting any of this would be useful, and I hope I can help, Dr. Matthew L.
