Dear fieldtrippers.

I am currently new to fieldtrip, and would like to analysis fMRI data with the toolbox. 

I started by following the instructions on "Getting started with fMRI timeseries data" (https://www.fieldtriptoolbox.org/getting_started/fmri/). However, when executing the command 

I got a resulting struct with the field "anatomy", which is a 4D double, but not "functional" as it supposed to be regarding the manual.

Moreover, when I proceeded with the remaining code trying to represent the 4D timeseries data as a source representation, I got an error saying

Arrays have incompatible sizes for this operation.

Error in ft_sourceplot>cb_redraw (line 1550)
if any([xi yi zi] > functional.dim) || any([xi yi zi] <= 0)

Error in ft_sourceplot (line 1106)

 How can I fix the problem?

Thanks in advance!
