Problems when trying to run REST v1.8

Hi all,

I am new to using REST_V1.8_130615 fMRI toolbox extension in SPM12 and am having some problems when trying to start the REST toolbox.
I am using Matlab version 2015a and SPM12 on Windows 10 64-bit machine.

I am able to start the REST toolbox however when I start by typing "rest" in the command window I get the following error

Warning: The DrawMode property will be removed in a future release. Use the SortMethod
property instead.

Error using matlabpool (line 27)
matlabpool has been removed.
To query the size of an already started parallel pool, query the 'NumWorkers' property of
the pool.
To check if a pool is already started use 'isempty(gcp('nocreate'))'.

Error in rest (line 77)
            CurrentSize_MatlabPool = matlabpool('size');

In the REST toolbox window when I click the "ReHo" button I get the "Regional Homogeneity" window that has two-buttons "KCC-ReHo" and "Cohe-ReHo".
When I click "KCC-ReHo" I get the following error

When I click "Cohe-ReHo" I get the following error

When I click the "ALFF" button in the REST 1.8 window I get the following error

When I click the "Viewer" button in the REST 1.8 window I get the following error

Error using sprintf

Please if anyone know how to solve these error that will be great. I also found sometimes errors when clicking ALFF and fALFF button.

Thanks much,
