saving struct array is slow and returns an error message
显示 更早的评论
i have a small struct array that when i try to save returns
Error using save
Error closing file
/Users/fchang/Dropbox/Public/smalldataset/fcProcessedStorage/201601-test-adf/s1/[fcSpotDetection]/spotMLEs/spotMLEs(BWY819-14_w2-FITC(WhiteTTL)_s1_t1).mat.
when i use try /catch around the save, there is no error message, and the file is successfully saved. first of all, it takes a long time, and second why is there an error message? i tried several save version flags and it does not matter for both problems.
linked is the workspace save (that also returns the error message but file is saved anyways)

Saving to networked files is often slow. If you have enough disk space it is usually faster to save to local disk and then to copy the saved .mat to the networked disk. For example,
tfile = [ tempname() '.mat' ];
destfile = '/Users/fchang/Dropbox/Public/smalldataset/fcProcessedStorage/201601-test-adf/s1/[fcSpotDetection]/spotMLEs/spotMLEs(BWY819-14_w2-FITC(WhiteTTL)_s1_t1).mat';
save(tfile, 'variable1', 'variable2', ...)
system( sprintf('mv "%s" "%s"', tfile, destfile) );
