[GSAS-II] Question about loading multi-histogram data into GSASIIscriptable

[Long Yang]

Hi all,

I am new to GSAS-II scriptable. I am trying to load the powder histogram data using `gpx.add_powder_histogram` but failed. The data file contains 6 banks TOF histograms together in one file. If use GSAS-II GUI, it can be loaded perfectly as in GSAS, but not work in GSASIIscriptable. The traceback is shown below.

Anyone knows how to do it? 
Or do I have to cut the file into 6 pieces of individual files that one file is one bank histogram?

Thank you!

Bests,
Long Yang
