HI - in theory you could feed any stats image into TFCE (the validity devil may be in the exact details of what else you're doing) - though in general in the world of permutation testing it's better to feed in normalised stats (t, z, etc).
Cheers

OK, I can use the fslmaths command effectively from MatLab with my own data.

But, does the input to TFCE have to be a t-map?
Can it be a Z-map?
Can it be a parameter map?

Thank you.

Hi - I'm not quite sure what you're asking - do you just mean how to get the
TFCE statistic image once you already have a raw t-stat image, using
fslmaths?
Cheers.

Dear Steve,
Thank you for the reply.
Could you point me to code that would make this calculation?

Hi - you would need to generate TFCE stats images *inside* the
bootstrapping, so that you generate a null distribution based on TFCE stats
- to give valid corrected and/or uncorrected pvals.

Cheers, Steve.

I have read that I can only use TFCE  with randomise results.

Is this still true?

I have used my own bootstrap procedure and would like to use TFCE with it.
Is this possible?
If so could someone provide some guidance to get me started?

When I run fslmaths -tfce on my Z-stat image I get an output where if
I use a threshold of 1000 I have nice results, but what is this image?

Thank you for any insight,
Jason
