[FieldTrip] Update - transfering TF data from SPM

[Duncan Astle]

Dear Vladimir,

Thanks for your help; I worked out what it wanted. 

Anyone who is interested should contact me and I will take them through it. 

Best,
Duncan

Dear Duncan,

You should look in the code how FT differentiates between different structures and what goes wrong. For instance it might be that it is confused by the fsample field that shouldn't be there. It's been a while since I did something like that and FT code has evolved with more stringent checks now.

Best,

Vladimir
