I cannot run the mean analysis
I am working on a meta-analysis of empathy and mirror neurons in psychopathy. However, I am having a lot of problems with the program. I am new to it, so any advice you can give me is welcome.

I already have the files with the coordinates where the groups had differences. In the SDM table editor I only added the Study variables, n1, n2 and t_thr. I ran the pre-processing successfully. Then I wanted to do the mean analysis, but I got the following error:

The program will close as this problem could cause fatal errors.

I think it has to do with the fact that I did not put the variables of mean1, mean2, sd1 and sd2. I did not do this because in no study did I find such data on differences in activation of brain areas. However, I think they are necessary. What can I do to know those data from the studies included in my meta-analysis? And if that is not the case, what should I do in order to continue doing the analyses?
Thank you very much, i really hope you could help me.
