Error when opening an ITM File generated by Surface Lab 7

[teolombardo]

Dear developer(s),

I was trying to use pySPM for reading ITM files generated by SurfaceLab 7.X. This is the version that creates the .itax files instead of the .ita, but, together with it, the software also prints .itm files, which I hoped could be read by pySPM. Is it incorrect?

In particular, I tried something very simple:

import pySPM AI = pySPM.ITM("test.itm", readonly=True)

But it raises the following error (if I try removing the readonly option, of course nothing change) :

MissingBlock Traceback (most recent call last) Input In [3], in <cell line: 6>() 2 path_test = path + "\2022_03_24_non_coated_NMC_spectrometry_positive_01_TL.itm" 4 print(path_test) ----> 6 AI = pySPM.ITM("test.itm", readonly=True)

File ~\AppData\Local\Programs\Python\Python310\lib\site-packages\pySPM\ITM.py:114, in ITM.init(self, filename, debug, readonly, precond, label) 112 except: 113 self.Nscan = None --> 114 self.spp = self.root.goto("propend/Registration.Raster.ShotsPerPixel").get_key_value()['int'] 115 try: 116 R = [z for z in self.root.goto('MassIntervalList').get_list() if z['name'] == 'mi']

MissingBlock: Missing block "/propend/Registration.Raster.ShotsPerPixel" with index 0

Thanks in advance for your help, I am really looking forward for using this library!

ITM files are huge, but if you find a way to share it with me I can try to see if I can help...
