[FieldTrip] ft_redefinetrial problem

[qi li]

Hi,

I have a fixed length experiment raw. I  apply ft_redefinetrial with
cfg.trl to epoch it into many segments. When this step is done, the
output.hdr.grad has different fields from the input field. More
specifically the pnt and ori field are gone thus cause trouble for the
later analysis.*  *I am using 12/23 version, is there a bug or it is
suppose to be so.

If I only want to separate the long data into segments, which command can
change only the time window while keeping all the other parameters
unchanged?

Thanks!

Qi
