Error on Jpeg2000 decompress

[Ohkyung]

Dear ImagJ users,

I having problem to open jpeg2000 format file created from Neurolucida.
I am using ImageJ 1.43t with Java 1.6.0_12 (64-bit) on Windows Vista
Ultimate x64 machine. The jpeg2000 file size is 177318 KB.

When I tried to open one of my jpeg2000 file utilizing LOCI Bio-format
plugin (Release: stabe 4.1, revision 5727, built 3 December 2009), I
got the following error message.


loci.formats.FormatException: Could not decompress JPEG2000 image.
Please make sure that jai_imageio.jar is installed.

Hi Ohkyung,

From the stack trace, it looks like you ran out of memory.

This can be a problem with JPEG2000 compressed files, because the
compression rate can be very high, meaning the uncompressed data takes much
more space than the file on disk. In your case, 173MB could become ten times
that (hard to say for sure without seeing your data).

How much RAM do you have allocated to your ImageJ? See Edit > Options >
Memory & Threads in the menu... you may need to set Maximum Memory higher.
Click that dialog's "Help" button for more details.

[Oky]

My computer has 16 GB memory. Right now, 4096 MB is allocated to
ImageJ. I will increase the size of memory allocation for ImageJ and
try to open the jpeg2000 format file.

Thanks for your suggestion!

Best regards,
Ohkyung
