What is the meaning of the I and C dimensions?
They are used in this file https://github.com/andresperezlopez/pysofaconventions/blob/master/examples/createTestFile.py and also inside the different SOFA database I am testing, but I can not figure out their meaning.
Thank you for the help
In the above mentioned file the variable SourcePositionVar
is created by means of sourcePositionVar = rootgrp.createVariable('SourcePosition', 'f8', ('I','C'))
Shouldn't it be sourcePositionVar = rootgrp.createVariable('SourcePosition', 'f8', ('M','C'))
? We expect a data that is number of measurements x dimensions (so for example for the MIT KEMAR database with 710 measurements and (azimuth,elevation,distance), we have 710 x 3)
Using the latest version of your API from PyPI (I assume that is identical to the current version in the repo?). Loading supposedly valid SOFA files like MIT KEMAR (http://sofacoustics.org/data/database/mit/mit_kemar_normal_pinna.sofa) or THK KU100 (http://sofacoustics.org/data/database/thk/HRIR_L2702.sofa).
Checking the validity fails by SOFAWarning: Missing Variable Attribute: ListenerUp.Units
and also some other attributes (havn't checked in detail which else yet).
The convention (https://www.sofaconventions.org/mediawiki/index.php/SimpleFreeFieldHRIR) says that these attributes are not mandatory, i.e. optional I suppose. I think we should modify the validity check accordingly?
