SOFA file dosn't work in Decoder

[fewege]

I have created a sofa-file using the SOFAconvertMIT2SOFA function. Now I want to use the rendered sofa-file with the IEM AdpativeBinauralDecoder (BETA) but the plugin gives me the following error: " Weights generation failed. Error: Generic error. Failed to load HRTF."

Since other sofa-files work the problem probably is my generated file.

I'll paste my code bellow. I would be greatful, if someone could help me on this.

Maybe also check if all components in the Data sub-struct exist and have the appropriate sizes and ranges.

The error from the Plugin is not very informative of course. But maybe it is related to the quadrature weights of the sampling grid? ... never mind, I don't think SOFA provides a standardized property to store the weights anyways, right? So I don't know what the plugin would do in that regard (they probably don't use the weights and do the transformation into spherical harmonics via the pseudo-inverse).

Hi, is this issue still open or can I close the topic?

[isfmiho]

Hi, if the issue still occurs I would like to reproduce it.

Can you maybe share an example project (eg. Reaper), including all necessary files, and with one working and one non-working SOFA file, so I can try to detect the specific difference that causes the error.

[isfmiho]

Issue cannot be reproduced. The problem might depend on the combination of your SOFA file, and/or on the plugin.
