- picks reasonable limits and ticks - uses latex for pretty fractions if necessary - replaces old labels produced by previous calls - does NOT autocorrect on zoom/pan/resize algorithm: - choose limits as smallest n such that pi/n < x_data_range - optional: increase n to next smallest "round" number - "round" means "power of 2" right now; could be a*b^n with a<b, 2^a*3^b, etc - choose step size as smallest d that ensures at least L tick marks I'm sure there are plenty of bugs.

- Hidden Markov Models for Molecular Motors
- License: Freeware
- Price: 0.00

Hidden Markov models are used to describe the "stepping" behavior of molecular motors, as measured by single-molecule fluorescence techniques. Our HMM implementation is more versatile than the one described by Milescu, et al. Biophys. J. 91:3135-3150 and can be used as a "blind" step detector or to find rate constants and step sizes directly from a measured time course of positions.

If the input is a bandlimited signal containing components at DC - 0.5Fs where Fs is the sample rate, SINCRESAMPLE will return the signal that would have been seen with a higher sampling rate (and the same filter settings). The algorithm depends on the fact that the bandlimited signal is completely defined when sampling at Fs.
