I have a set of MRI dicoms and STL model images, I am wanting to create binary segmentation maps from the models, which i can do fine manually using these steps:

- 

```
Go to Segmentations module

```

- 

```
Create new segmentation node

```

- 

```
Change master to Closed surface

```

- 

```
In Import/Export section import the model node to the segmentation node

```

- 

```
Export visible segments to binary labels map

```

But i have a lot of cases i need to do, so was wondering what is the actual code being executed to load in the STL files and convert them to a segmentation map? So i can automate the process

Thanks.

See several examples of how to automate these conversions in the script repository: [https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Segmentations](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Segmentations)

Did you please find the code for this automation, I tried it with slicer but it’s so slow
