DESCRIPTION

This program is used to extract parameters from temporal wavefronts described in (.lst) fan output files from dart simulations.

-a:TimeLo:TimeHi Calculate an area map between TimeLo and TimeHi. By default, the area for the full time will be used. -d:TimeLo:TimeHi:thresh Calculate the action potential duration map between TimeLo and Time Hi as the total time over which the waveform exceeds thresh. By default, thresh=-60 mV. -e:TimeLo:TimeHi:TimeInc Threshold data to create excitable gap maps. This option was designed for use with the h-gate. Nodes at which h is below 0.1 are set to 0. Nodes at which h is above 0.1 are set to 1. Nodes which are on the boundary between 0 and 1 and the deriviative is negative are set to 2. Output is written to files eg.Time.pot at increments of TimeInc. TimeLo and Time Hi as the -i:thresh calculate the isochrones based on the temporal derivatives. Activation times are determined from transmembrane potential waveforms as the maximum temporal derivative. Threshold default is 0.0. -m:thresh extract maximum values. -p:TimeLo:TimeHi:TimeInc extract isovalues between timeLo and timeHi at increments of timeInc and route the output to files Time.pot. Note the isopotential map at TimeHi will route to stdout instead of to the file TimeHi.pot. By default, TimeInc=1.0. -q:TimeLo:TimeHi:TimeInc extract the present isovalues. With the -p option, vmax attempts to determine isovalues by interpolating based on the derivative. That interpolation can cause errors when the derivative is changing rapidly. This option acts like -p, except no interpolation is attempted. -r:TimeLo:TimeHi:TimeInc extract isoderivatives between timeLo and timeHi at increments of timeInc and route the output to files d.Time.pot. Note the isopotential map at TimeHi will route to stdout instead of to the file d.TimeHi.pot. By default, TimeInc=1.0. -t:nodeLo:NodeHi:nodeInc extract the wavefronts at the specified nodes between nodeLo and nodeHi at increments of nodeInc. -v:TimeLo:TimeHi extract the maximum positive derivatives (V.max).: Calculate an area map between TimeLo and TimeHi. By default, the area for the full time will be used.
-d:TimeLo:TimeHi:thresh Calculate the action potential duration map between TimeLo and Time Hi as the total time over which the waveform exceeds thresh. By default, thresh=-60 mV. -e:TimeLo:TimeHi:TimeInc Threshold data to create excitable gap maps. This option was designed for use with the h-gate. Nodes at which h is below 0.1 are set to 0.
