But it gives the below error: Quality check: 6s Warning: Unable to interpret TeX string "D:\software\spm12\tpm\TPM.nii " > In spm_orthviews>redraw at 1459 In spm_orthviews>redraw_all at 1466 In spm_orthviews at 320 In cat_main_reportfig at 157 In cat_main at 770 In cat_run_job at 786 In cat_run_newcatch at 15 In cat_run>run_job at 720 In cat_run at 434 In matlabbatch\private\cfg_run_cm at 29 In cfg_util>local_runcj at 1688 In cfg_util at 959 In cfg_ui>MenuFileRun_Callback at 703 In gui_mainfcn at 96 In cfg_ui at 53 Warning: Unable to interpret TeX string "..tes\_1.50mm\Template\_1\_IXI555\_MNI152.nii " > In spm_orthviews>redraw at 1459 In spm_orthviews>redraw_all at 1466 In spm_orthviews at 320 In cat_main_reportfig at 157 In cat_main at 770 In cat_run_job at 786 In cat_run_newcatch at 15 In cat_run>run_job at 720 In cat_run at 434 In matlabbatch\private\cfg_run_cm at 29 In cfg_util>local_runcj at 1688 In cfg_util at 959 In cfg_ui>MenuFileRun_Callback at 703 In gui_mainfcn at 96 In cfg_ui at 53 ------------------------------------------------------------------------ CAT Preprocessing error for scan1_t1: ------------------------------------------------------------------------ Undefined function 'spm_ov_mesh' for input arguments of type 'cell'. ------------------------------------------------------------------------ 421 - cat_main_reportfig 770 - cat_main 786 - cat_run_job 15 - cat_run_newcatch 720 - run_job 434 - cat_run 29 - cfg_run_cm 1688 - local_runcj 959 - cfg_util 703 - MenuFileRun_Callback 96 - gui_mainfcn 53 - cfg_ui ------------------------------------------------------------------------ Failed 'CAT12: Segmentation' Reference to a cleared variable cat_err_res.
