感谢回复!我看了一下空白那部分的值都是0,应该不是阈值的问题。
但是发现在进行转换的时候
srcvol = /home/lab/CAP8/CAP8_1.nii
srcreg = /usr/local/freesurfer/7.4.1/average/mni152.register.dat
srcregold = 0
srcwarp unspecified
surf = white
hemi = rh
reshape = 0
interp = nearest
float2int = round
GetProjMax = 0
INFO: float2int code = 0

有一个警告信息提示分辨率不匹配的问题

请问老师映射后有部分区域值为0的问题有可能是因为分辨率的问题吗
