It doesn't look like it is really a permission problem as the user can write in /tmp/ and when pausing in the caa_download routine I can see that matlab created a folder /tmp/.

In caa_download/ get_zip_ file (line 650) > In extractArchiveE extractArchiveE ntry (line 100) Warning: Permission denied to create file Speed up read operations by setting the 'ConvertEpochToDatenum' name-value pair argument to true, to return CDF epoch values as MATLAB serial date numbers. By default, cdfread creates a MATLAB cdfepoch object for each CDF epoch value in the file. The CAA folder created whilst download Cluster cdf data files is empty. Read CDF Epoch Values as Serial Date Numbers.
