It worked!

1) First I used mri_convert and converted my sig.nii files to a chache.gii
file.
2) I downloaded the files and unpacked them.
3) I went to directory fs_LR and used this command:

caret_command -deformation-map-apply
fsaverage.R.registered-to-fs_LR_fix.164k_fs_LR.deform_map
METRIC_NEAREST_NODE ../..j/Practice/cache.gii
../../Practice/fsaverage_to_FS1441.nii

4) Then I went to directory pals_R and used this command:

caret_command -deformation-map-apply
fsaverage.LR.registered-to-pals_R_fix.74k_pals_R.deform_map
METRIC_NEAREST_NODE ../../Practice/fsaverage_to_FS1441.nii
../..j/Practice/FS1441_to_PALS1449.nii

I did not face any error

5) Then I went to "Map Functional Volumes to Surfaces".  I used "Add
Volumes From Disk" and I picked the "FS1441_to_PALS1449.nii" file.

6) in "Map to Spec File" I picked the
pals.R.register-with-fs_LR.74k_pals.spec that exists in pals_R folder

7) Then when used File>Open Spec File and openned the same spec file
(pals.R.register-with-fs_LR.74k_pals.spec) I faced this message:

 Error map_data_1_8_Nov_2013_15_05_50.metric contains a different number of
nodes than PALS_B12.R.AVG-FIDUCIAL_MRITOTAL.74k_pals.coord

Any idea what is wrong?
