External Email - Use Caution
Dear Douglas,
And is there a recommended way to compute a z value from the cluster p-value?
You can use a p-to-z conversion; I'/m not sure it means much though
With voxel-wise measure of z value, do you mean a z value of a particular voxel, for instance, the voxel with the maximum p value in a cluster?
It could be that or the average. I don't know what you are trying to do here so I can't be much help
Thank you very much.
Regards,
Agurne

There is no z value for the cluster itself, but you could take the cluster p-value and use it to compute a z value. Or do you want a voxel-wise measure of z value?

Is there another way to obtain a Z value or alternatively, a t-value?

In order to obtain the information for displaying the results in the paper, I am looking at the cluster summary table. I have seen that some papers include the t value in addition to the p value, cluster size and coordinates, but how can I obtain the t value? Does it appear in the cluster summary table or elsewhere?
