accessing simlog data for calculation

Hi.

I have a subsystem where it has 12 cells, each has its own temperature. I used simlog to plot temperature of cells individually, it worked. As I need to calculate the mean temperature of 12 cells, I used 'mean' block, it is good. I use scope to view the results. Now, I need to calculate and plot the mean temperature value of 12 cells (I cannot use the graph from scope window, because later in my work I will have to process more data. So, I am trying to get this done using .m file)

Is there a way to calculate and plot mean value of 12 cells using simlog command? say for example, I assign a variable for each cell temperature value accessed via simlog command (cell1 = simlog_ohne_PCM.Cell_cooling.Cellassembly.Cell2.Thermal_Model1.T; cell2= ...., cell3= ......, and so on, later avg temp = cell1+cell2...+cell12/12)

Could anyone suggest here?
