LoadHKL dialog.
Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| Filename | Input | string | Mandatory | Path to an hkl file to save. Allowed extensions: [‘.hkl’] |
| OutputWorkspace | Output | PeaksWorkspace | Name of the output workspace. |
Loads an ASCII .hkl file to a PeaksWorkspace.
File has same format that works successfully in GSAS and SHELX from ISAW:
hklFile.write(‘%4d%4d%4d%8.2f%8.2f%4d%8.4f%7.4f%7d%7d%7.4f%4d%9.5f%9.4f\n’% (H, K, L, FSQ, SIGFSQ, hstnum, WL, TBAR, CURHST, SEQNUM, TRANSMISSION, DN, TWOTH, DSP))
HKL is flipped by -1 due to different q convention in ISAW vs Mantid.
FSQ = integrated intensity of peak (scaled)
SIGFSQ = sigma from integrating peak
hstnum = number of sample orientation (starting at 1)
WL = wavelength of peak
TBAR = output of absorption correction (-log(transmission)/mu)
CURHST = run number of sample
SEQNUM = peak number (unique number for each peak in file)
TRANSMISSION = output of absorption correction (exp(-mu*tbar))
DN = detector bank number
TWOTH = two-theta scattering angle
DSP = d-Spacing of peak (Angstroms)/TR
Last line must have all 0’s
Example
import os
wsPeaks = LoadIsawPeaks('TOPAZ_3007.peaks')
SaveHKL(wsPeaks, Filename='testHKL.hkl')
wsHKL = LoadHKL('testHKL.hkl')
#remove the file we created
alg = wsHKL.getHistory().lastAlgorithm()
filePath = alg.getPropertyValue("Filename")
os.remove(filePath)
