Save a PeaksWorkspace to a ISAW-style ASCII .peaks file.
The PeaksWorkspace consists of individual Peaks, each of which has an individual PeakShape relating to the way the workspace has been integrated. The PeakShape information is not saved out in the ISAW peaks format. To save the full peak information, use the NeXus format SaveNexus.
import os
# Prepare a PeaksWorkspace to save.
# Create a run workspace
ws = CreateSampleWorkspace()
# Create a peaks workspace
pws = CreatePeaksWorkspace(ws)
# Add two peaks to the peaks workspace
AddPeak( pws, ws, TOF=100, DetectorID=101, Height=1 )
AddPeak( pws, ws, TOF=200, DetectorID=102, Height=2 )
peak = pws.getPeak(1).setPeakNumber(2)
peak = pws.getPeak(2).setPeakNumber(3)
# Save the peaks workspace to a file in the user's home directory
isawPeaksFilePath = os.path.expanduser('~/MantidUsageExample_ISawFile.peaks')
SaveIsawPeaks( pws, isawPeaksFilePath )
# Read the saved file back in
