RELEASE_NOTES

Release notes/change log for VERTEX

See also the README file

--------- Version 0.95b (Jan 24 2018) --------

Bug fix: distributedGenerator algorithm introduced in previous release now returns correct instantaneous pairwise correlation value

--------- Version 0.95 (Jan 14 2018) --------

Added alpha-shaped synaptic currents and conductances

Added functionality to slice synapses outside model boundary for cylindrical shaped models

Added two utility functions for pre-generating spike trains: poissonGenerator() and distributedGenerator(). poissonGenerator() generates poisson spike trains, while distributedGenerator() generates arbitrarily correlated spike trains by selecting spikes from a pool of poisson spike trains (See Rudolph & Destexhe 2006)

Adds option to "stretch" neuron morphologies according to the model Z dimension

Bug fixes: fixed a bug that broke the simulation when number of neuron groups = 1, but number of layers > 1, fixed a bug affecting I_syn recording, minor fix to neuron positioning code, fixes bug throwing error if storeCompartmentPositions not specified in SimulationSettings, fixed bug in user entered structure checking for current/conductance inputs, fixed some cylindrical model bugs

--------- Version 0.94 (Feb 1 2016) ---------

Added ability to specify parameters in Matlab Map objects as well as structures (the Map is converted to a struct internally).

Added to the help system: functions to print info on physical units and to print a list of available user functions

Added ability to record synaptic currents on a per (postsynaptic) neuron basis

Added tutorial 8 (introducing the neuronDynamics() function)

Updated tutorial 1

Bug fixes: fixed a bug in specifying whether multiple pre-post synapses per neuron are allowed, fixed bug that broke the simulation if the user did not specify to record v_m or I_syn in RecordingSettings

--------- Version 0.93 (Nov 8 2015) ---------

Added specific checks to prevent synaptic time constants being intialised to <= 0

Bug fixes: fixed i_step input current problems (now works in parallel and if timeOn = 0), fixed a synaptic current summation bug for point neuron models with no synapses, fixed a bug that broke the simulation if the sample rate and maxRecTime were incompatible, fixed a bug that broke the simulation if some neuron groups had input currents specified but others didn't

--------- Version 0.92 (Jul 14 2015) ---------

Added support for new Matlab parpool() implementation (VERTEX automatically chooses whether to use matlabpool() or parpool() based on detected Matlab version)

Now allows passive parameter values to be specified per-compartment in a vector

Bug fixes: fixed bug that caused z-positioning errors for neurons in some cases, fixed error leading to extra spikes being plotted by plotSpikeRaster() for parallel simulations, fixed the loadResults() documentation

--------- Version 0.91 (Nov 06 2014) ---------

Added neuronDynamics() function for testing neurone model dynamics prior to a network simulation. Also added step current input model.

Added possibility to modify runSimulation() to allow multiple simulation runs within runSimulation(), with model parameters changing but dynamical variables not being reset between runs

Added functionality to allow loadResults() to return the LFP due to each (postsynaptic) neurone group independently

Added functionality to plotSpikeRaster() to plot spikes from a subset of neurons, set the marker size, and x-axis limits

Bug fixes: fixed minor spike recording bug, corrected setRandomSeed() behaviour, corrected LFP calculation (missing minus sign means previous LFP calculations would have had the wrong sign)


--------- Version 0.9 (Jun 14 2014) ---------

First public release, as described in the paper but with added random number seeding control
