Hi everybody,

    I am new user of Freesurfer,I simply take five procedures to process my data ,after I read the wiki on the website. The five procedures including:

 1. mri_convert one-dicom-file-from-series blobby.nii.gz

 2.recon-all -i blobby.nii.gz -subjid blobby –all

 3.recon-all -s <subjid> -qcache

 4.make_average_subject.

 5.qdec

Now, my questions are:

1.In our e-mail ,you often talk about recon-all, why did I never across question about it ?

2. I tried to run the qdec-tool, but experienced some problems . I got different thickness in one area.
In detail:
    1. When I open the qdec.table.dat  ,the thickness is different from the thickness got from the display in Find Clusters and Goto Max, I really do not know why?
    2. Did I get the same results from two different qdec.table.dat , one qdec.table.dat has 34 Continuous Variables but the other had only one Continuous Variable ?

    3.Why did the display from qdec smaller than the examples in the wiki on the website?

Such as the pictures follow.

I guess part of my problem is that I'm having trouble understanding exactly how to use the freesurfer.  Can you try to give me a sort of layman's explanation?

 Thanks for your answer!
