Misfunctioning of importData method in Livelink.

Dear all,
I would like to ask you the following. I am facing problems in using the importData method in Livelink.
More precisely, using Livelink, in Matlab I am able to read a model, create inside Matbal a interpolation function over the mesh of a set of data and save the interpolation function in the Comsol Model. When it's time to import the data, the problem comes out. In fact, these are the lines to define the properties of my interpolating function:
model.func('value').set('nargs', '3');
model.func('value').set('defvars', true);
model.func('value').set('source', 'file');
model.func('value').set('filename', '/amd/smana3/root/vol/vol1/cmcs/tricerri/Comsol/MatlabScripts/associatedData.txt');
model.func('value').set('interp','linear');
model.func('value').set('sourcetype','user');
Then to import the data, if I use the model.func(tag).importData() command (as suggested in the guide) when I open the model (that has been modified in Matlab) in Comsol I am not able to plot the interpolating function. If I just define the filename and then, just import the file using Comsol (therefore I remove the importData command from Matlab) then, I can plot the interpolating function.
I have not found any guide about importData. Do you know how to use it? What am I missing?
Many thanks,
Paolo Tricerri

Hi Paolo,
Maybe you can try this:
model.func.remove('int1');
model.func.create('int1', 'Interpolation');
model.func('int1').set('source', 'file');
model.func('int1').set('filename', Input_filename);
model.func('int1').importData;
model.sol('sol1').run;
importData works only when "Input_filename" is the full path : 'C:\Users\you\Desktop\...\xxx.csv'
Good luck.
