      Hi,

      I’ve recently started using MEA and would appreciate some help understanding the R script parameters.

      Regarding the sampRate parameter: My understanding is that this should match the frame rate of the analyzed video files (in my case, 25 FPS). Is this correct?

      However, I noticed that some papers mention running MEA analysis at 10 FPS(Paulick et al., 2018; Ramseyer & Tschacher, 2011). I’m wondering if this is usually done by downsampling the output from a higher frame rate (e.g., 25 to 10) within the analysis, or if it implies the source videos were originally recorded at 10 FPS?

      Thanks in advance for any insights!

      Hi,

      yes – insert the sampRate of your video. This needs to match your video. otherwise you will get wrong timinig information.

      The other papers just based their analyses on videos with different frames per second (fps). –> just use the fps-settings of your video

      cheers, Fabian
