Dear experts  
I have just installed in a different PC the new version of Slicer.  
I used to use the version 4.8 in another PC.  
I never had problems in upload the surfaces produced with freesurfer as models.  
However in the new version with different PC Slicer tell me that It could not read the pial file.  
Could you help me please  
Best regards

Lorenzo

Thanks to @Sunderlandkyl and NIH funding to Harvard PNL, FreeSurfer support has greatly improved in Slicer-4.11 and to facilitate easier and more frequent updates, a dedicated [SlicerFreeSurfer](https://github.com/PerkLab/SlicerFreeSurfer) extension has been created.

You need to install the SlicerFreeSurfer extension before importing/exporting FreeSurfer data. Try the [new importer](https://github.com/PerkLab/SlicerFreeSurfer/wiki/Using-FreeSurfer-Importer).
