Dear Christian,
the "Bad tissue contrast" error usually points to the use of a non-T1 image, which is sometimes impossible to segment. CAT12 is primary thought for T1 images. Sometimes, this error might also occur for quantitative data (e.g. R1).
However, if you have set the ignore error flag in the defaults, CAT12 will move on with the next files even if this error occurred.
Best,
Christian
