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.

[CAUTION: Non-UBC Email]

Hi All,
There is now an importer for Bruker .brml files. 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.
Best,
Bob

Yes, it is open source, I have attached it in case Brian or Bob are interested 
in it.  At the moment it is written as a filter so I can convert a bunch of 
data at once.

I'd be happy to see your code, is it open-source? It would probably be more 
useful to Bob though, to save him some time.

Hi Matthew:

I have written a python program that extracts a gsas file from the Bruker brml 
files.  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.

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,
