I don't have anything to do the Heller-style conjunction. But you can use mri_concat with the --min option to compute the max p-value over a stack of conditions (our sig maps are actually -log10(p), so the min gives you the max p).

Hi,

I load Version 4.0,5, and it works!!!!!!!!!!!!! Thanks!!!

Yet, I just have another question now: Is it possible to 
conduct a conjunction analysis like implemented in SPM5?

If not, is it valid to simply take the p-maps in the surface space and 
compute the pooled dependent p-values according to Heller et. al 2007 (NeuroImage 37 1178-1185),
and if so are there Matlab readers for the p-map files?

thanks, schüss

We ran several subjects using version 4.0.4 and now need to reinstall freesurfer to finish the processing.  Is there a  linux centos4, 32 bit version available somewhere?

Thanks,

Tricia Merkley

Iris,

I think this bug was fixed in v4.0.3.  We can also just post tkmedit for
you to download if you tell me your distribution, ie, type:

cat $FREESURFER_HOME/build-stamp.txt

Hi Iris,

what version are you using? I tracked down and fixed a bug like this some 
time (a year?) ago.

cheers,
Bruce

Dear FreeSurfers

I use the command:  <tkmedit-sess -s vpnXY -aparc+aseg -analysis ampmod -c AmvsSIN> and want to mark a point at special Talairach coordinates at this brain. When I type in the coordinates e.g. -46 -19 8 and press RETURN the the Numbers change to e.g.
-46 -92 15. I dont found a possibility to mark the talairach coordinates I want. Can you help me?
Thanks!

Dear list,

I wish to obtain information about a list of surface vertices, including 
their coordinates in MNI305 and Talairach spaces. Is there any tool that 
can provide this information at the command line? I can get the 
information by loading tksurfer and selecting the vertex, but this is 
slow for a long list of ROIs.

I have found that the mris_info tool will give me the real coordinate of 
a surface vertex, but there is a discrepency between the information it 
provides and that obtained from tksurfer. For example, for a certain 
vertex, mris_info gives the coordinate (25.2, -93.5, 12.5). Loading the 
surface into tksurfer and selecting the same vertex gives a location of 
(24.90, -93.27, 12.26). The locations are obviously close, but the 
difference can't just be due to rounding errors.

Padraig
