Rigaku SmartLab XRD Data (.rasx)
.rasxRigaku SmartLab Studio II (X-ray diffractometer control/acquisition software)
What it is
A ZIP archive holding a plain whitespace-separated text profile plus an XML index — the native scan output of Rigaku's SmartLab XRD line.
Who produces it
X-ray diffraction labs running Rigaku SmartLab instruments under SmartLab Studio II.
What we read / what we don't read
What we read
- The first profile (Data0/Profile0.txt): column 0 as 2θ, column 1 as intensity
- root.xml, used only to detect how many scans/profiles the archive contains
What we don't read
- Additional profiles beyond the first, when root.xml reports more than one Data/Profile entry — same reasoning as .brml: merging separate scans would silently produce a wrong graph, so AltaiPlot warns instead of guessing
How to import it into AltaiPlot
- Open AltaiPlot and drag your .rasx file onto the window, or use File → Import.
- AltaiPlot detects the Rigaku signature (a ZIP with a Data0/Profile0.txt entry) and hands it to the bundled Python reader automatically.
- The first profile's 2θ/intensity curve is imported directly.
- If the archive contains more than one profile, a banner tells you only the first was imported.
