Hello, I recently can't save figures as .fig files. it worked until a few weeks ago but suddenly I'm getting an error. I can save the same figure as .png or .jpg, but specifically .fig is not working anymore. The error: "input must be a row vector of characters". I changed the file name to only letters but it still didn't work. this is my code:

> f=figure;
> plot(courtship_index),
> cd('/Users/dgal/MATLAB_results/160901_courtship/') 
> saveas(f, 'courtship_index', 'fig')

and I received this error chain:

   Error using fileparts (line 43)
  Input must be a row vector of characters.
Error in savefig (line 53)
  [fpath,fname1,ext] = fileparts(fname);
Error in saveasfig (line 6)
savefig(h, name);
Error in saveas (line 140)
    feval( ['saveas' format], h, name )
Error in trim_function (line 67)
saveas(f, 'courtship_index', 'fig')

in a separate case I plotted a different figure and tried to save it by clicking "file" -> "save as" on the figure itself, but got the same error: "error using fileparts (line 43). input must be a row vector of characters".

What happens if you simply try fileparts from the command line--

fileparts('courtship_index') % ?

Also what does

which fileparts

return and there's always

clear fileparts

then see what happens...

dpb: that did not help. here is my code:

fileparts('courtship_index')

ans =

> which fileparts

/Users/dgalili/Documents/MATLAB/JAABA_Release_v0.6.0/filehandling/fileparts.m

> clear fileparts

> savefig(f, 'courtship_index', 'fig')

Error using fileparts (line 43) Input must be a row vector of characters.

Error in savefig (line 53) [fpath,fname1,ext] = fileparts(fname);

Which release of MATLAB are you using?

Are you certain you're using the fileparts function included in MATLAB? Does this show any fileparts.m file outside the toolbox/matlab subdirectory in your MATLAB root directory?

which -all fileparts

The bug was caused because JAABA's savefig clashed with Matlab's savefig. the developer renamed JAABA's savefig and saveas now works fine. thanks for all the help.
