Hello,

I need to work with image files having .svs files. These files can be viewed by using the imagescope software available in the http://www.aperio.com/default.asp site. These files use JPEG 2000 compression. These files are of sizes 400~800 MB. I am currently using version 2009a. I can't load the files in MATLAB. Could you please help me with a solution? Is the size is problem or the format?

Thanks Sabrina

MATLAB cannot open svs with its tiff reader if JPEG2000 compression is used. I suggest using VIPS or NIP2 to convert the svs file to BigTiff or another image format can read first.

In case people are still referring to this old post - reading SVS images with JPEG2000 compression is now supported in R2020b:

JPEG2000 file format was not supported until R2009B, the version after what you have.

I meant .svs extension. Ok if I upgrade my MATLAB version will I be able to work with these files?

Walter Roberson 2011-11-9

If they use a .svs extension but are completely JPEG2000 internally, then should will be readable -- though you might have to give imread() a clue as to what kind of image they are.

You should be able to get a trial version to test compatibility with.

There is no specific support for .svs files in any MATLAB version that I can remember.

I tried to open an .svs file but it shows up as totally empty. Is there anybody who tested this ? Thanks Walid

I'm having the same issues. I am using R2010b version and trying to figure out how to use Matlab for various file types. Have you been able to figure out how to read the svs images?
