Is there a way to avoid repetitive calculating about OpenMEEG

Hello Everyone!
Recently, I analysed different patients' scalp eeg in Brainstorm and used same ICBM152 imaging template. When I conducted Souce Analysis, however, I need Compute head model by OpenMEEG everytime. You know, it is always time consuming.
So, I want to know, is there any way to avoid repetitive calculating in this step. I want to use other patient's OpenMEEG result which was coming from same ICBM152 template, but I don't know how to do this.
Anyone can help me?

You can copy a head model file (iconHeadModel) to another subject just like any other file:
Right-click > File > Copy / Paste, or the keyboard shortcuts Ctrl+C / Ctrl+V.

This should be done if and only if you are using the same anatomy and the same sensor positions.

You can also copy one OpenMEEG head model to all the other folders and subjects with a single click:
right-click on the head model > Copy to other folders/subjects.

If you want to do this programmatically, the function to use is db_set_headmodel.m:
