Hi,
I have a gui that runs perfectly fine on a Mac with 2017a, when I run it on win2017a (prior to compiling it) I get numerous errors. This one however I do not understand at all
Undefined operator '>' for input arguments of type 'cell'
I can trace it back to the line which reads in the data...
data=readtable(files(k).name,'FileType','text','Delimiter','tab','TreatAsEmpty',['UND. -60001','UND. -2011','UND. -62011']);
the Mac and Windows versions run this differently, the Mac honors the TreatAsEmpty, note on the Mac it requires double quotes (" ") around each argument to exclude as empty whereas the Windows version called that an error and wanted single quotes, it then does nothing with them. This leads to the array being a table in the Mac version of the GUI and a cell in the Windows version, I just can't see why some fundamental matlab basics would be so different between the versions?
Any ideas?
Best regards
Steve

expression1 = 'M\d\R\d\_';
Z(k)= regexp(RN,expression1,'match');
%%Assign variables to data
vel_NS=data.Velocity_ms;%-NS.....Nozze Scan data
% vol_NS=data.Volume_pl;
% traj_NS=data.Trajectory_deg;
% noz_NS=data.ExpID;
vel_NS(vel_NS > 10)=NaN;%for awful data exceeding 10m/s this will remove them
end

Where you used "" as the delimiter, you used a facility available in R2017a and later; your other system must be running an earlier version.
