troubleshooting topoplotER

[Christian Hesse]

Hi Sameer,

given that the error you report involves a call to the function
CREATELAYOUT it seems that you are using a relatively old version of
Fieldtrip. There were some changes made in early March to how layouts
are handled using a new function PREPARE_LAYOUT. I recommend that you
download the latest version of FT - if this error persists, please
let me know.

Also, it is worth periodically checking the "recent changes" section
of the FT website to see if there are any updates that are relevant
to you.

Regards,
Christian
