Dear Ping,
For your second request, either you are programming in macro language and use the Roi.setProperty(key, value) and Roi.getProperty(key) methods:
http://wsr.imagej.net/developer/macro/functions.html#R
or in java and use the setProperty(java.lang.String key, java.lang.String value) and getProperty(java.lang.String property) methods:

My best regards,
Philippe

Objet: 回复: draw ROIs on different slices

Hi Kees,

Thank you so much for your email,
For the first question, would it be possible to save the ROIs (drawn on different slices) into a mask image volume, with the slice information matching the original image volume?

For the second question, I meant to see if it is possible to assign a different label to different ROI, for example, I draw one ROI and label all the pixels inside with "1", and another ROI with all pixels labeled with "2", this way I can recognize different ROIs.

Thanks again,
Ping

Dear Ping,

Check in the ROI Manager menu under More > Options if 'Associate "Show All" Rois with slices' is selected.

I am not sure what you mean with your second question about label images.

Best wishes

Kees

Subject: draw ROIs on different slices

Hello everyone,

I wondered if ImageJ is able to draw ROIs on different slices and it also remembers the slice information. Currently it does not seems that ImageJ include the slice# information, all the ROIs basically are overlapped. Also not sure if ImageJ is able to make label images.

Thanks for any hints.
