Dot indexing is not supported for variables of this type

I'm trying to load a file onto matlab from Opensim, but it shows this error on this line - timevector = rawIK.data(:,1);

%% Load Data

filename = 'C:\...\MoBL-ARMS OpenSim tutorial_33\ModelFiles\InputFiles_module5_scaleIK\IKreach.mot';

delimiterIn = '\t';headerlinesIn = 7;

rawIK = importdata(filename,delimiterIn,headerlinesIn);

timevector = rawIK.data(:,1);

@Pretty Mariam Roy : please show the complete error message. This means all of the red text.

Please provide a link/information on the exact file format (not just a name, but an actual description of how the data is stored in the file), or upload the file by clicking the paperclip button.

The file is stored as a motion data file (.mot) after carrying out inverse kinematics on a model in opensim. I wish to filter the result and is therefore using filter.m.

Here is snapshot of the .mot file I'm trying to load.

What type of variable is it?

[Mariam Roy]

rawIK is a cell

If your cell has strctures inside, you should first mention the row and column of the cell then access the structure inside a cell.

rawIK{4,1}.data
