Primary file extension not defined in legacy EMU template file

[krisbara]

emuR version 2.2.0

I am using the function convert_legacyEmuDB() with my file (.hlb). It appears an error 'Primary file extension not defined in legacy EMU template file'.

However, it creates a folder (name.hlb_emuDB) with the file containing the next information:

{
  "name": "vp01-HLL-linn0.ton",
  "UUID": "4d3d5807-6618-423d-8338-5c8158da0943",
  "mediafileExtension": {},
  "ssffTrackDefinitions": [],
  "levelDefinitions": [],
  "linkDefinitions": [],
  "EMUwebAppConfig": {
    "perspectives": [
      {
        "name": "default",
        "signalCanvases": {
          "order": ["OSCI", "SPEC"],
          "assign": [],
          "contourLims": []
        },
        "levelCanvases": {
          "order": []
        },
        "twoDimCanvases": {
          "order": []
        }
      }
    ],
    "activeButtons": {
      "saveBundle": true,
      "showHierarchy": true
    }
  }
}

The function 'summary' shows:

Name:    vp01-HLL-linn0.hlb 
UUID:    c9fa6d92-0b33-49ce-86ab-43243cede98c

It would be great if you could help me to deal with this issue. I need this file to convert into TextGrid afterwards.

You will have to address the error: Primary file extension not defined in legacy EMU template file as the conversion function doesn't know which audio/media files to look 4. The reason a directory is created is because it initially converts the tpl file to the DBconfig.json file then keeps on going. The generated emuDB ist basically broken and can not be regarded as a working database (simply delete and retry). You will prob. have to fix/add this line to your .tpl file:
