Hello all, my question in a nutshell is the following:
What determines the size of matlab's fig files? I encountered an extreme increase in the size of my figure files and I would like to know which I might have changed.
I am currently facing the problem that, after coming back from holidays, the figures I am saving with matlab increased in size about 50-fold.
I am working with brain imaging data and use "fieldtrip" to produce 3D images of brain activation. The data sets used for plotting are and have always been huge (200 - 5000 MB), however the resulting figures have always been tiny (2 - 5 MB).
Lately - and I can't think of any reason for it - the .fig files I am saving are almost as large as the original datasets I am plotting (and also larger for large datasets although the resulting 3D image should be the same independent of the dataset size). I noticed this because Matlab suddenly asked me to add the -v7.3 switch to my save command because the file size started to exceed 4 GB (while being less than 5 MB before).
Since my problem may be specific for the datasets I am plotting (and I cannot post 4GB datasets or figures here) I phrased the above question in a very general way. With your answers I might be able to solve my problem.
I use Matlab 2013b and Matlab 2013a, the issue occurs with both. My figures are plotted using ft_sourceplot (fieldtrip toolbox) on a UNIX and a Windows system.
Thanks for your help, maybe you can even comment on my actual problem or on what kind of info I should post to give more insight into the problem.
