Hey Annat,
I´m just starting with R and your commands could be a great help for my
Pongo-data. Would be very very great if you would share them!!
Many greetings,

Hi
I wrote functions in R that do this (align along the midline plane, and
either average left and right or fill in NA's based on the other
side).I'll be happy to send it to you and anyone else who's interested.
I've been meaning to put them online but I don't even have a website yet
and no time so far to make one...
Best,
Annat
