Help quantifying Fibers and cells to fibers contacts..

[ZazaTSRI]

Hi All,I have never used ImageJ before..so I`m quite lost.. I have Scanning Electron Microscopy images of cells and a "tubular" matrix; I would like to be able to quantify the number, diameter of all the fibers in the image, and as well measuring the contact points between the fibers and the cells..I have tried NeuronJ and other neuronJ-like plug-ins..but with not that much luck..As far as I understood with NeuronJ I will have to manually find all the path of the fibers, where I was looking for something more automatic.. Any help will be much appreciated!
