Cannot load publicly available nwb files with Matnwb (but works with Pynwb)

[chrismkkim]

Hello,

I'm trying to load the nwb files from the paper:
Kim, J. H., Daie, K., & Li, N. (2025). A combinatorial neural code for long-term motor memory. Nature, 637(8046), 663-672.

The nwb files are available in
https://dandiarchive.org/dandiset/001188/0.251008.1146

I was able to load the files in Python with Pynwb by installing its default version. However, in Matlab, loading the nwb file nwbFile = nwbRead(filepath) with Matnwb produces following errors.

It would create a variable type types.core.VectorData in the m-file getNeurodataTypeInfo.m. But, this variable type does not exist in Matnwb version 2.10.0, since VectorData.m is defined under +types/+hdmf_common, not +types/+core. If I check the schema version of the nwb fileutil.getSchemaVersion(filepath), it's 2.7.0. I'm not sure if the Matnwb version should match with the schema version, but I've checked Matnwb version 2.7.0 and VectorData.m is also defined under +types/+hdmf_common.

I wanted to ask if there are ways to properly load these nwb files. I can get around the above errors by forcing the variable type to be types.hdmf_common.VectorData, but then there were additional error messages that appeared.

Below is the error message I get from Matlab. I'd appreciate your help!
