[FieldTrip] Issue with ft_plot_mesh

[Schoffelen, J.M. (Jan Mathijs)]

Hi Mahmoud,

The argument ‘vertexcolor’ into ft_plot_mesh should be a column-vector, with the number of elements equal to the number of positions in the sourcemodel (i.e. the number of rows in bnd.pos). You did not specify in your question what the dimensionality is of the variable leadfield (nor whether it is a matrix, a cell-array, or something else).

Good luck,

Jan-Mathijs

Hello,
I obtained the lead field matrix using both openmeeg and bemcp
When I tried to visualize the result in a similar pattern like the openmeeg example
I got the following error:
Error using ft_plot_mesh (line 488)
Unknown color specification for the vertices

I used the following function: figure; ft_plot_mesh(bnd, 'vertexcolor', leadfield(:,1))
with bnd being a structure have the points and the trianglar elements
