Dear Joaquim

Thank you for your answer.
I find the WIN64 had been reported a bug in combine imges.https://www.nitrc.org/forum/forum.php?thread_id=8264&forum_id=3982
I replace the binaries of my package, It's success!

So If I want to Conduct the meta-analysis of all studies, including only the single combined t-map for the study with two contrasts.
I should

• Created A new folder.
• Convert the combined T-map.
• Put the converted T-map and t_Chun2015.var_reduction.txt with other txt in a new folde.
• Preprocessing again

How to use the t_Chun2015.var_reduction.txt?
I tried to change the file size from 0.65 to 0.8, which is determined by the assumed correlation and number of images, and found pp_Chen2015_var.nii.gz changed. I can think of combine images do not change the images just add them up?

Best,

Zheng Hui
