    2121I tested a couple smaller thresholds and the number of filaments seemed to converge to this value, N = 909.

     23There are a lot of clear filamentous structure that Amira is missing -- so I tried playing in the filament editor of Amira, which instead of a threshold now let's you auto trace using a windowing function. This windowing function lets you control contrast.

     33This suggests that the first way of doing the tracing was using the color map to find filaments, and then letting you adjust the threshold for this. This let you control I suppose what filaments to capture -- you just make them stand out in the color map. Looking at the Fig. 5 in the algorithm paper (Fouard et al 2006) seems to suggest contrast is what is being traced.
