A file representing a model created on a catalogued tomogram will be stored in a predefined position. For instance, a model named someModel created by Dynamo in one of its catalogue-based tomogram viewers for the volume indexed as 2 in a catalogue named my Catalogue will be automatically stored in the position:


Now, if you have produced a model object myModel independently of the catalogue system, and want to embed it and assign it to a catalogued tomogram, you might have the temptation of just saving it as


While this will work for many functionalities, this is not totally correct, as the catalogue needs to preserve some internal links.

  1. Assign the model with the dcm command dcm
    dcm -c myCatalogue -i 2 -am myModel.omd
    for a models contained in a file myModel.omd, or
    dcm('-c', 'myCatalogue', '-i', 2 ,'-am', m);
    if the model is contained is an workspace object m
  2. Alternatively, you can tell the catalogue to relink all the files found in the models folder of one or more volumes.
    dcm -c myCatalogue --relinkAllModelFiles
    XX: not yet implemented!

Technical information

The link between a model and its 'volume' entry happens over the property cvolume in the model object. If you want to imitate manually the action of the flag am, you just need to extract the corresponding 'cvolume' object of the catalogue and assign it to the 'cvolume' property of the model before saving it.

When working inside a catalogue and accessing a model file from a volume, Dynamo will normally relink the model so that it points to the calling volume. For such operations, the above described protocol is not necessary.
