LoadSampleDetailsFromRaw v1¶

Summary¶

Loads the simple sample geometry that is defined within an ISIS raw file.

Properties¶

Description¶

The SPB struct within an ISIS raw file defines 4 fields that describe the basic geometry of the sample:

• e_geom;
• e_thick;
• e_height;
• e_width.

The meaning of the last three are dependent on the flag value e_geom, which defines the sample shape as one of 4 basic shapes:

• 1 = cylinder: radius = e_thick = e_width, height = e_height;
• 2 = flat plate: as named;
• 3 = disc: radius = e_width, thickness = e_thick;
• 4 = single crystal.

The values are stored on the sample object within the workspace.

Usage¶

Example:

filename = "HRP39180.RAW"
ws = Load(filename)
LoadSampleDetailsFromRaw(ws,filename)

s = ws.sample()
print("Geometry flag {:.0f}".format(s.getGeometryFlag()))
print("Dimensions H,W,D {:.0f},{:.0f},{:.0f}".format(s.getHeight(),s.getWidth(),s.getThickness()))

Output:

Geometry flag 2
Dimensions H,W,D 20,15,11
