Hi,
Give the 3dMVM_validator beta a try to test your -dataTable.
https://afni.nimh.nih.gov/pub/dist/doc/htmldoc/tutorials/3dMVM_validator/3dMVM_validator_overview.html
It won't be correct for the 3dLME testing, but it should give you a hint for what is wrong with your -dataTable specification.
It is probably the quotes or some spaces somewhere.
Can you post some of your -dataTable?
thanks, Justin
