[Freesurfer] what is inflating to sphere rms error?

Dear Freesurfers,

I am new to freesurfer and I am afraid of doing something wrong, so I am writing to ask is this error indicating something wrong with my data? Any help is appreciated. below are detials of my question. Thank you!

I used freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 with this command fsl_sub -N cch recon-all -i ${i} -s FSsub${i:3:5} -all

I checked the O file from fsl_sub and it said at the end "recon-all -s FSsub12534 finished without error at Thu Jan 23 15:44:35 CST 2014 done" Seems it's OK

then checked the e file from fsl_sub (standard_in) 2: Error: comparison in expression Seems this is a problem of fsl_sub, According to https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2012-May/023961.html I guess I can ignore it?

Then I checked the recon-all.log file and find a lot of "error", Someone asked this question and got the answer "We see this mysterious message sometimes...usually things are fine". So when and why get there errors and does they always fine? https://mail.nmr.mgh.harvard.edu/pipermail/freesurfer/2011-October/020810.ht...

the "rms radial error" and "distance error " are below or see my attached log file.
