I first ran tbss_1_preproc *.nii.gz and that went well. Now when I enter tbss_2_reg -T it gives me the following: Error: target image /usr/share/fsl/data/standard/FMRIB58_FA_1mm not valid Usage: tbss_2_reg [options] Target-selection options - choose ONE of: -T : use FMRIB58_FA_1mm as target for nonlinear registrations (recommended) -t <target> : use <target> image as target for nonlinear registrations -n : find best target from all images in FA I thought that -T automatically used FMRIB58_FA_1mm......if not how do I obtain this? Sorry for the simplicity of my question I am new to all this. Thanks in advance for the help. Cindy --------------------------------------------------------------------------- Stephen M.
