External Email - Use Caution oh, you should have used --fwhm 3 on that first command, and if you want 5mm then use --fwhm 5

Dear Dr. Douglas N. Greve,

Thanks to you, I could have a binary disk approximately 3mm in radius by the codes you told me (*MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be* https://secure-web.cisco.com/1xywEFLDR_oeRyXfrDIuVJrFffRVWUUzwyhfbDv55ykMN9FJgie6__XDC2GpxVaa8T2Z7KW5d4qThvYZ2_XellON0dMciuzWymp40M9eZteQz2fMbSjbMrUuL5MZ_4d8ok44jGsTZXAuqQe2-lggUR9zLk9EZkr0AsKKD7XF96UttFpnByKOHhX1NjQ0ZCKt3PWW9gb_rcAdgNQxrcaRlyPFGQey5oRavzUZvlZyHASXZb8NMXLmQALSy7QeqshPDRwrLc0ckKC2K8X2QIhYpXQ/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg74761.html <https://secure-web.cisco.com/1z0F3-vP1KDJI6B_AsTyKAaKNmMd0vO7tGkwv_YiAe4mgtFL1QdTiYs_dYZa0SNYmBNh1h2ge_bd6h98_TjHFMZx8lfVf63LrKeca6bpHJqS3efsPrABmWu40PwE_1bXSb2a1Mtv0R2-CjohzV52lOG68h2lN3pBTXfpuar6V01OlX-ZOuMA0aMQl0OxzxU7uGWZRbNeUFiUdR2dqlzLBm98JI_0xPxY7tVbtcYEGfmjJ4NRcdsEjFHhLRp6JVv4h241u3JIeOcZrWmJ69BHaQm7ygPDdDOpDsxQNHVOTHeJVBDigROxNKREccAKsjdVP/https%3A%2F%2Fwww.mail-archive.com%2Ffreesurfer%40nmr.mgh.harvard.edu%2Fmsg74761.html>):

mri_volsynth --dim-surf fsaverage/surf/lh.white --pdf delta --delta-crsf ${vertexno} 0 0 0 --0 delta.mgh
mris_fwhm --i delta.mgh --o delta.sm3.mgh --s fsaverage --hemi lh
mri_binarize --i delta.sm3.mgh --min 0.5 --o delta.sm3.bin.mgh

I have sincerely appreciated your help.

Now I'm wondering how to modulate the radius. I guess I can do it by adding --fwhm option to mris_fwhm command, for example:
mris_fwhm --i delta.mgh --o delta.sm3.mgh --s fsaverage --hemi lh --fwhm 5
At the end, I will get a binary disk with 5mm in radius. Am I right? And does this mean that --fwhm 3 is default for mris_fwhm? How could you define 3mm?

Kind Regards,
Andy (Junghyun) Kim
