Construction of masks
Dynamo uses several types of masks in different pipelines.
Masks are used in Dynamo for several purposes: indicating the active part of the template for alignment, restricting the area of the aligned particles that will count for classification, avoiding FSC artifacts, placing aligned averages back in a tomogram....
In some tasks, the masks are expected to be simple geometrical shapes. In other occasions, it might be necessary to have a finer control on the process of constructing a mask.
