Error when trying to open .dm3 file

[JulioAzcarate]

Hi ... I'm newer using "diffraction-ring-profile" ... this program is very well, ... good job!!

However, I have a problem to open .dm3 files. This is the error shown in console:

/home/julio/Desktop dif-pdf_0009 .dm3 /home/julio/Desktop/dif-pdf_0009.dm3 {'acq_date': b'8/9/2018', 'acq_time': b'9:52:17 AM', 'name': b'FEI Tecnai', 'micro': b'', 'hv': b'200000.0', 'mag': b'220.00000000000003', 'mode': b'DIFFRACTION', 'operator': b'', 'specimen': b''} (0.019381428137421608, b'1/nm') Traceback (most recent call last): File "diffraction_ring_profiler.py", line 776, in OnOpen self.openimage() File "diffraction_ring_profiler.py", line 800, in openimage self.img_contrast = (dm3f.contrastlimits[0] - dm3f.imagedata.min(), dm3f.contrastlimits[1] - dm3f.imagedata.min()) File "/home/julio/Programas/Binarios/diffraction-ring-profiler-master/dm3lib_v120.py", line 738, in contrastlimits low = int(float(self.tags["%s.ImageDisplayInfo.LowLimit" % tag_root])) KeyError: 'root.DocumentObjectList.0.ImageDisplayInfo.LowLimit'

How can I solve this issue???

Thanks in advance

It seems like your instrument isn't setting the low constant limit in the .dm3 file.

Can you share the .dm3?

I think you can attach it here in a zip file.

Hi @bcolsen ... thank for your time.
I couldn't find for attach a file here, but I linking the zipped .dm3 file to download it.

Thanks in advance.
