Description

There is an unusual problem happened. I got 2 MDF files which recorded by DataLogger, one of them could be read well but the other one reported a bug

File "D:/program/12222.py", line 20, in
dt = mdfreader.Mdf('Data2F002Data2F002.mdf')
File "D:\Anaconda\envs\test\Lib\site-packages\mdfreader\mdf.py", line 150, in init
self.read(file_name, channel_list=channel_list,
File "D:\Anaconda\envs\test\Lib\site-packages\mdfreader\mdfreader.py", line 409, in read
self.read3(self.fileName, None, multi_processed, channel_list,
File "D:\Anaconda\envs\test\Lib\site-packages\mdfreader\mdf3reader.py", line 947, in read3
buf.read(channel_set, self.fileName) # reads datablock potentially containing several channel groups
File "D:\Anaconda\envs\test\Lib\site-packages\mdfreader\mdf3reader.py", line 702, in read
data = self.load_unsorted(name_set=channel_set)
File "D:\Anaconda\envs\test\Lib\site-packages\mdfreader\mdf3reader.py", line 773, in load_unsorted
buf[channel_name][index[record_id]] = self.fid.read(nBytes[channel_name])
IndexError: index 18 is out of bounds for axis 0 with size 18

I try to fix it but I got no idea of changing the length of index. Following image is the details of my data. Hope you could help me to fix it. Thanks!

Hi,
sorry for the delay, I was in vacation. You are trying to read an unsorted file version 3.x.. I must admit it is not greatly tested.
Thanks for sharing the screenshot. However, if I cannot compare with what is expected, like record structure from MDFValidator, it is too complex for me to troubleshoot. Or you can share the file if you can ; if you want to remove confidential info, you can scramble it following the script from Daniel : #189 (comment)
