color map differences in group mycrostate

[Pouyarabiei]

**Hello everybody
**
I am conducting mycrostate analysis using pycrostates. I am comparing two groups: one with pain and one without.
Using the same processing steps, my final maps are wierd so that I have mycrostate map with vise versa color map between the groups. For example, the pain group is like ‘RdBu’, my healthy group is ‘RdBu_r’

See my plots below, please.

I was wondering if anyone has faced such an issue and can guide me.

To the best of my knowledge, microstates are computed at points of maximum global field power (GFP). GFP is insensitive to positive/negative direction of the peak/valley and only cares about the deviation from zero. Hence, the sign of the microstates can be arbitrarily flipped when estimated on different datasets.

Thank you for the response.
