Hi,</div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
GSAS-II has no means of reading Bruker raw4 files - they never made the format documentation available (I suspect they don't know what it is anymore). PowDLL (Windows only) can read raw4 files & make a gsas format data file readable by GSAS-II but all metadata
(e.g. temperature) is lost. It is not clear this includes multiscan raw4 files. The brml file is potentially far more digestible.</div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
A Bruker brml file is in fact a zip file of a collection of xml files. GSAS-II does not have currently an importer for that, but one could be written based on the Panalytical importers for powder and reflectometry data (.xrdml) and some of the other importers
know how to use zip files. The powder patterns in the Bruker brml file are all "RawDatan.xml" (n = integer 0,1,2... for as many scans that are in the file); some appear to be setups & others have the actual scan - these are much larger. There are also various
"nameContainer.xml" files within the brml (aka zip) file that may contain useful information about the data set. To access all this, change the brml extension to zip, unzip the result, and then use an xml reader to examine the xml file contents (MS Edge or
Chrome will read it just fine - one can see the file layout directly - it's all text). From that an importer can be written in python that will process a multiscan brml file & recover the desired metadata as well. </div>
<div style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
To whoever takes this on; it will be much appreciated by the GSAS-II user community and we'd very much like to include this importer in GSAS-II.</div>

I’m not familer with all the details of the GSAS-II Module for Bruker .raw & .brml imports: you see the docs and source here (section 20.3.5):
<a href="https://urldefense.us/v3/__https://gsas-ii.readthedocs.io/en/latest/imports.html__;!!G_uCfscf7eWS!bR02qPdZlmP9aYfS8uRGMxA7yLoDeyWSzsg6KY91wzjxwMwtMXmPgPxzbKhz9gCWy3oseCWGqQgrVhg2CwP6pkVSscqqtX3v-Xg$">https://urldefense.us/v3/__https://gsas-ii.readthedocs.io/en/latest/imports.html__;!!G_uCfscf7eWS!bR02qPdZlmP9aYfS8uRGMxA7yLoDeyWSzsg6KY91wzjxwMwtMXmPgPxzbKhz9gCWy3oseCWGqQgrVhg2CwP6pkVSscqqtX3v-Xg$</a>
There might be a bug, but I’d also be surprised if the module was designed to handle the case of brml files which contain many distinct datasets or scans in the single zip file (like your VT case). Moreover, the details of the .brml files seem to sometimes vary depending of the exact types of scans in the .brml zip (continuous scan, static scans, etc). Even Bruker's own DIFFRAC.FileExchange program doesn’t always work.
In situation like this, I typically use DIFFRAC.EVA to just export all the datasets from a multi-scan brml as separate RAW or XY files. I believe you can select all files in the data-tree within EVA and export with a single click. Then, it is rather more simple to plot and / or analysis the data using non-Bruker software.

> I'm trying to do a temperature calibration for my MTC-Furnace based on the Bruker manual. So I used the automation system to get an MgO measurement at each relevant temperature, and then I was going to use GSAS-II to do Ritveld on it to get the temperature. However, when I try and open any *.brml file with more then one data set in it, I get the following error:
