This walkthrough shows how to reuse the geometric computations performed on a single model onto a larger set of models.

We can use a synthetic tomogram containing different tubular structures. In this catalogue, we open the tomogram with dtmslice, and then define a filament model following the usual procedure, so that we end up with a single model containing a set on points.

We will now define a workflow, i.e., a method of converting points into crop_points.

We open the workflow editor of the active model, and start operating the steps, checking graphically the result of each parameter selection. We create first a backbone, selecting the interval between backbone elements.

Creation of the backbone

And check how the results looks like:

right click to get the plotting options of a step
created backbone traversing the points

We then proceed for the next step: selection of the interval (in pixels) between two consecutive crop points.

Selection of interval between crop points

And check again the results:

right click to get the plotting options of a step.
created points and orientations

... not forgetting to save the model into the catalogue. The model will contain the generated crop_points and also the parameter values used to generate them.

Saving the model

Now can save the workflow itself, probably providing first a different name than the default.

Provide a name for the workflow. It will be saved later into the catalogue


Once the workflow defined on the first model is defined we can move to a different filament and pick its extremal points with controls [1] and [2]:

Next filament is chosen

and then define a new filament model, and click on their points. But in this case, afterwards we save the model without further edition


and move to the generation of a further filament model

three filament models

Now, the catalogue should see three models inside this tomogram entry.


If we open the tomogram with the volume list manager, we will get a list of those models. We should see that the first we created does contain some crop points, but the other two don't.
