Exception has occurred: KeyError x 'data'

[dervinism]

I get this error by executing this line:

derivedData = mat73.loadmat('some_mat_file.mat')

I cannot reproduce this error, for me it works fine.

1. Could you upload the file in question and send a link?
2. Additionally, could you please post the full traceback so I know where the error appears?

Hi,

The file can be downloaded via the link: https://drive.google.com/file/d/19937d9LRN6YU-WWxzvIEhsPZIYnhLGEc/view?usp=sharing

That pretty much was the full traceback. The actual traceback is this:

Exception has occurred: KeyError
'data'
  File "/mnt/c/Users/44079/code_repositories/convert2nwbPyNnx/localFunctions.py", line 239, in getSpikes
    derivedData = mat73.loadmat(animalDerivedDataFile)
  File "/mnt/c/Users/44079/code_repositories/convert2nwbPyNnx/convert2nwb.py", line 101, in <module>
    (spikes, metadata, derivedData) = getSpikes(derivedData, animalID, sessionID[iSess], tbl)

Thanks for providing the file!

It seems like there is some problem with loading the sparse matrices in /dataStruct/seriesData_positive/M190114_A_MD_s201901221911037/shankData/shank1/sp

this seems to be a sparse matrix format that I did not encounter yet

I'll see if I find time to fix it.

in the meantime as a workaround, you can try to catch the exception in line 147 in core.py by adding

                    except KeyError as e:
                        unpacked = None

@dervinism does the newest fix at #53 and the newest release fix the problem?
