Editing LUT

[Manuel Jose Muñoz Martinez]

I'm working with ultrasound images, theese are 8bits grayscale images.  
I need to assign a color to a range of grays instead a single gray  
value.Is there any way to achieve this?.
Thanks in advance.

Use the LUT Editor (Image>Color>Edit LUT), which is described at

    http://rsb.info.nih.gov/ij/docs/menus/image.html#lut-editor

I'm rather new to ImageJ, so forgive me if the answer to this question is obvious:
 
I need to save a large sequence of images, then open them later to run Analyze Particles on them.
Analyze Particles requires binary images, and it seems to want the particles to be black and the background white.
 
How can I save images as binary images?
 
Thanks,

ImageJ does not support single bit images per se, however, 8-bit images
that only are black and white (0 and 255) (for example the result of
"Make binary") are valid binary images when saved and restored as 8-bit
images.

Good afternoon,
I am a physician who is a neophyte in measuring grey scale.  I wish to measure the grey scale at various levels in a tendon statistically and compare the means etc.  Statistical manipulation is easy relatively for me.

I will select consistent sites and use the linear tool that will give me a mean etc and list values.  I will export the list value into Excel and put the other "list values"  in column next to it.

First is this correct?

Second, do I have to collect each sample separately and export or can i create one file with all the data in it before exporting.

Sorry if this is dumb

Regards

Simon
