Analysis

Leak subtraction

• 3 methods of defining leak data on-line and off-line
• On-line and off-line subtraction of scaled leak trace, including capacitive transients
• Subtract specific leaks on-line in current clamp using a selection of dynamic clamp models

Measurement plots

The trend and measurement plot function in Signal generate graphs of measurements taken from the recorded data both on-line and off-line. For each frame selected, measurements are taken from individual or multiple events and plotted as X and Y coordinates. Typical examples would be the generation of an IV curve or measurements from multiple action potentials.

Curve fits

Fit mathematical functions to original or leak subtracted data and trend plots.

• Fit types include:
  • Exponential, first or second order
  • Gaussian, one or two
  • Polynomials from first to fifth order
  • Sigmoid (Boltzmann) curve
• Gives best fit coefficients and an estimate of confidence
• Display fit coefficients in trend plots
