Extracting information with getImageInfo()

[Gareth Howell]

Hi I am trying to extract information from the getImageInfo() command.
How can I obtain, for instance the number of channels in an image. I am using the Deltavision Opener plugin, which opens all the images in a multicolour dataset as a single stack but the channel number is within the image info. If i getImageInfo() the channel number are displayed on the line "NumofWavelengthes: 3". How can i get this number '3' to put into the rest of the macro as a variable? I feel i'm missing something obvious, sorry!

Thanks

Hi Gareth,

you can try
  getInfo("NumofWavelengthes");
If it is a number, do ParseInt or ParseFloat on the result.

Hi Gareth,

I would suggest using Bio-Formats and scripting it from your macro:
http://openmicroscopy.org/site/support/bio-formats4/users/imagej/#macros-and-plugins

First of all, Bio-Formats might address your "opens all the images in
a multicolour
dataset as a single stack" problem. (And if not, we would be interested in
a non-working sample so we can fix it.)

Secondly, if you still need to access metadata, Bio-Formats was built with
that in mind. See this article for details:
http://openmicroscopy.org/site/support/bio-formats4/about/#bio-formats-metadata-processing

Bio-Formats comes built in with the Fiji distribution of ImageJ (
http://fiji.sc/).

Regards,
Curtis
