[Mrtrix-discussion] streamline counting

[Markus Gschwind]

Hi,

You can use the command "track_info" that gives displays among others the
value "count"

You can also read the command into a variable "count" using the following:

count=`track_info mytrack.tck | grep '\<count:' | awk '{ print $2 }'`

Hope this helps!
Markus
