[caret-users] question for caret

[Jinhui Wang]

Dear John Harwell,
Thank you for your answers very much. AAL template is in the MNI stereotaxic
space (here it is a nifti format of spm5).

I have seen section 5.1 and tried every step as what the tutorial tells.

Following the suggestion in the tutouial, i don't run the mapping algorithm
and use the pre-computed  ***.metric in the result/subdirectory to view the
result which is as a example. Everything works. However, i also try to run
the mapping algorithm to generate new metric files and use them to view the
reuslts. Unfortunately, when i choose file/open data file and specify the
new generated metric files, a dialog box appear name "choose column to
load"? What does this mean?  And if i ignore it and press ok, an error
happen for the differnt number of nodes contained between the metric file
and the **coord file.

 God. Please give me a hand. ^_^
