imodextract(1) General Commands Manual imodextract(1) NAME imodextract - Extract objects from a model into a new model. SYNOPSIS imodextract [-g | -d] list_of_objects input_model output_model DESCRIPTION Extracts a subset of the objects from an IMOD model and places them into a new model. This can be much more convenient than making a copy of a model and deleting objects one by one inside 3dmod. The list of object numbers, numbered from 1, can consist of comma-separated ranges of numbers, for example 1-3,6-9,13,15. You can specify either objects to be retained or objects to be deleted when making the new model. If the -g option is given before the list, then the list is treated as specifying object groups, which can be created in the Model View Object List dialog. This list of groups (numbered from 1) will be translated into a list of objects which will be extracted without reordering them. The groups need not be mutually exclusive; only one copy of an object is made. The new model will have just the specified object groups, but appropriately modified with the new object numbers. If the -d option is entered, then the list specifies objects or object groups to be deleted, and all the rest of the objects will be extracted. Object groups will be replaced when just extracting by object group (without the -d option), but otherwise existing object groups will be maintained. The new model will have the same number of object groups, with objects not extracted removed from the groups, and object numbers modified appropriately for the rest.
