Hi everyone,

Currently, Im using the modules Extract Centerline and Curved Planar Reformat, in order to obtain a straightened volume from a data set DICOM.

I have to do that for several examples, so I wondering if is possible to create a python script to automate the process; just charge the segmentation and points like the imput of the script, and obtain a straightened volume like the output.

Its possible this? Which is the way/syntax to interact with the input and output of each module? There are some examples about that? Or maybe an anorher way?

The workflow is:  
inputs\_1 (points and segmentation)  
Center line code  
Output\_1(center line)  
Inputs\_2(center line and data)  
Straightened volume  
Output\_2(Straightened volume)

Thanks, Lucas.

Yes, this should not be too hard, even if you are completely new to Slicer. After you completed the Slicer programming tutorial (I would recommend [this one](https://www.slicer.org/wiki/Documentation/Nightly/Training#PerkLab.27s_Slicer_bootcamp_training_materials), but there are many more on youtube), you can have a look at examples in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html) and self-tests in VMTK and other extensions and ask here if you have any specific questions.

Thanks! Finally, I could understand how to call or work with other modules from my script.

In the case of the module _curved planar reformat_, I imported the module and then I copied and edited the test case in terms of my variables and preferences. This also allowed me to understand precisely the importance of the logical class.
