SyntaxError: unsupported data type on compound datasets

[ethicalvats]

Can not read the compound dataset

getDatasetType is returning H5O_TYPE_DATASET
getDatasetDimensions returns correct dimensions [1] in this case
But both readDatasetAsBuffer and readDataset are throwing the errors.

Please can you help me with this, thanks

Yep, I'll look into it, thanks for the report

[rimmartin]

Hi, can you provide an example? It almost looks like a table. There are more entries where the compound dataset members are listed

[ethicalvats]

Hi @rimmartin I am using the http://millionsongdataset.com/pages/getting-dataset/ . You can download the 1% sample (~2 GB) and try that out?

[rimmartin]

Ah thank you, I'll do that tonight and learn much more

                 var group=file.openGroup("metadata");
                 var childType=group.getChildType("songs");
                 var dsType=group.getDatasetType("songs");
                 console.log("type "+dsType+" "+HLType.HL_TYPE_TABLE);

output:

type 2 2
tableInfo 20 1

getDatasetType is returning HL_TYPE_TABLE. songs is a table and can be read as a lite table http://hdf-ni.github.io/hdf5.node/ref/tables.html

                 var readTable=h5tb.readTable(group.id, "songs");
                 for(var fieldIndex in readTable){
                   console.log(readTable[fieldIndex].name);
                   console.log(readTable[fieldIndex][0]);
                 }

shows the field names & cell values. Checking for missing datatype handling...
