Unable to exportgraphics or saveas: The value of 'destination' is invalid.

Hello matlab community,

I am trying to save my figures both in fig and png format. I was using these commands before without any problem but I started to get these errors:

Here is an example script I used to try:

a=[1:10]

b=[11:20]

plot(a,b)

saveas(gcf,'ab.fig')

exportgraphics(gcf,'ab.png','Resolution',600)

Saveas error:

Error using save

Unable to write file ab.fig: No such file or directory.

Error in matlab.graphics.internal.figfile.FigFile/write (line 32)

save(obj.Path, obj.MatVersion, '-struct', 'SaveVars');

Error in savefig (line 83)

FF.write();

Error in saveasfig (line 6)

savefig(h, name);

Error in saveas (line 153)

feval( ['saveas' format], h, name )

Error in untitled2 (line 4)

saveas(gcf,'ab.fig')

Exportgraphics error:

Error using exportgraphics

The value of 'destination' is invalid. Unable to create output file 'ab.png', No such file or

directory.

Previously I had problem using xline and I was using 'restoredefaultpath rehash toolboxcache' to fix it.

Would it be connected to each other somehow? How can I fix this problem?

Thank you for your time!

savefig(gcf,'ab.fig')

Try using savefig

if I try

savefig(gcf,'ab.fig')

I receive the below error:

Error using save

Unable to write file ab.fig: No such file or directory.

Error in matlab.graphics.internal.figfile.FigFile/write (line 32)

save(obj.Path, obj.MatVersion, '-struct', 'SaveVars');

Error in savefig (line 83)

FF.write();

Error in untitled3 (line 4)

savefig(gcf,'ab.fig')

What is the current directory? Do you have OS permission to write in that location?

Previously I had problem using xline and I was using 'restoredefaultpath rehash toolboxcache' to fix it.

Try this again, It may be the reason, as i dont get any errors with both commands when i run it online. Which version are you using ?

Hello,

My directory is as in the below and I used to save figures to that directory before without any problem. Maybe it is a naive question but how can I check my permissons ;?

I checked directory with 'cd' and 'pwd' but I do not what I am supposed to see about permission.

/Volumes/INTENSO 1/Field Data/FD_08.2019-07.2020/Z_DO/Met_2019_2020/Resp01

I have found this question about the related problem but I do not want to change any setting without knowing what it is since I am not very good at Matlab.

Hello @VBBV and @Stephen23,

Somehow the problem is solved.

I tried 'restoredefaultpath rehash toolboxcache' again and it is working again.

I am using R2022b and recently I have these kind of troubles time to time. They are fixed either with restarting matlab or using the above command. But I do not know the source of the problem.

Thank you for your support.

"how can I check my permissons ;?"

Check with your OS for that location. For example:
