openByte function not used?

Hi,

As mentioned in the error above I should use openBytes to handle the image. I am but it is not used, why is this?
Would very much appreciate some feedback on my code overall as well

Hi Albin,

the main issue is that the image you are loading is too large to fit into a single byte array which is limited to 2GB. If you are working with large XY images, you do not want to load the whole planes is not recommended (unless you are working with small resolutions images). Instead you should open the image in smaller tiles - see also https://docs.openmicroscopy.org/bio-for ... hlight=2GB.

At the API level, this means you want to use openBytes with values of x,y, w and h specifying a region smaller than the 2GB limit.

At the command-line level, you want to use the crop option to load tiles rather than entire planes i.e.

Code: Select all

$ BF_CP=/Users/Hedwall/bioformats/tools/ISQReader.jar /Users/Hedwall/bioformats/tools/showinf -format ISQ -crop 0,0,1024,1024 /Users/Hedwall/Desktop/C0003094.ISQ


Best,

Thanks! -crop is what I was looking for but now it keeps complaining about my readPlane() and I don't see the reson why. Is there any other method which behave like readPlane which I should use instead?
