transmit

Compute stats like transmission ratio for paired recordings. The spikes on chan1 are triggers, which are the time reference for the transmission window. If a spike falls within the transmission window on chan2, the trigger spike is counted as a transmitted spike. Spikes on chan1 are valid triggers only if they and their associated transmission window fall completely within the analysis interval defined by start and period.

Options:

• stat - write statistics to a file:
  1. infile - input file name without path
  2. group_name - name of analysis group
  3. ntrials - number of trials in group
  4. ntrig - number of triggers (valid spikes) found on chan1
  5. ntrans - number of times a trigger spike had one or more spikes in the transmission window on chan2.
  6. tr - transmission ratio = ntrans/ntrig
  7. sr1 - mean spike rate of chan1
  8. sr2 - mean spike rate of chan2
  9. cnt2 - total number of spikes for cell 2 (useful for contribution)

Parameter definitions:

• chan1 - first channel name.
• chan2 - second channel name, set equal to chan1 for ACG.
• start - start time for analysis epoch (sampling units)
• period - duration of analysis epoch (sampling units)
• win0 - start time of transmission window, relative to spike on chan1.
• winn - duration of transmission window (sampling units)

Example:

#
#  Prob of spike on chan2 in a window relative to and given spike on chan1

chan1 unit0
chan2 unit1
