I see, you want a histogram of a group of fibers. 

please visit the website-FAQ, where you can find the fiber data file
format; then you can read the fiber files, and get all infomation you
needed.

Yes, but isn't that the mean fiber length?  I'd like the length for each
fiber.

hi, 

after fiber tracking, clicking "fiber statistics" button, you can find
the fiber length in the pop-up windows.

That would be great!

I have to confirm Hangyi, but I believe a converter that can read a
tract
file, read the length of all stored tracts, and save the length of each
tract, is needed. 

Luke, have you ever written such an IDL file before?

Dear Matt,

I'm not sure if DtiSudio can provide a histogram of fiber length. It
should
be possible to extract such info from the stored tract file using IDL or
Matlab codes.

Hi all,
                How do I get an a measure of the length of each fiber?
I'd
like to do estimate the distribution of fiber lengths in some tracking
that
I'm doing.
Thanks,
Matt
