"Magnetic lasso"-like tool

Vera, Pedro L.
Greetings all:
I'm using ImageJ to measure DAB immunostaining intensity and I would like to trace (using a mouse) and select certain areas for measurement. Currently, the freehand tool works but it's very cumbersome and also fairly innacurate. Adobe Photoshop has a "magnetic lasso" tool that outlines and snaps to differences in pixel intensity and I have found it very useful for the kind of tracing that I am doing. Is there a similar plugin for ImageJ? I have searched the plugin list but have been unable to find one.

Thanks.

Pedro

The Fiji package has blow\lasso tool that works quite ok, tough they  
are announced as non-fully functional.
I think it similar to what you are looking for.

Re: "Magnetic lasso"-like tool

Vera, Pedro L.
Thanks for the suggestions. I installed the LiveWire plugin, since it seemed like it would do what I was looking for. However, I'm getting all kinds of errors (both in a windows box and a linux box). Following are the error msg (from the windows install). Btw, I'm running ImageJ 1.43f. It seems that the java version is a problem, but I don't get any other error msg when I run ImageJ.

I would appreciate any suggestions on how to fix this.

It is been some time since I tried last, but I also had problems using the
LiveWire plugin (under linux).

ImageJ's magic wand has recently been enhanced by means of a tolerance setting
(double click on the magic wand icon). It is probably not what you are looking
for, but it might help anyway.

BTW, when I read postings from other users trying to quantify dab intensity I
point them to this very informative message (last part) posted some time ago
to this list:

https://list.nih.gov/cgi-bin/wa?A2=ind0902&L=IMAGEJ&P=R18412&I=-3

I hope it helps.

G.

Hello,
the plugin needs java 1.6. I don't know the version from the site,
please contact the author for information about it.
If it doesn't work with java 1.6, you can try the version that comes
with "mri cell image analyzer" from
http://www.mri.cnrs.fr/index.php?m=42
if you don't mind to install a lot of stuff that you didn't want (make a
backup of your imagej folder before installing). You can start the
LiveWire 1d or 2d from the Tracing toolset.
Best regards,
Volker B├Ącker
