Interpreting the results of conjunction analysis

Dear all,


I'm new to SDM meta-analysis. I'm conducting a conjunction analysis for two functional meta-analyses using different tasks to identify overlapping regions. I used the multimodal function in SDM-PSI v. 6.23 beta


In the output folder, there are result folders analysis_neg and analysis_pos. Within these two folders, there are maps named corrp_voxel and corrp_voxel_neg (the same applies to tfce-corrected p). I would like to know what these two maps represent within each of the positive and negative result folders. For example, is analysis_neg\corrp_voxel_neg the map for overlapping the negative results from both meta-analysis A and meta-analysis B? I struggled to find a detailed explanation in the user manual.


Thank you.
