New CESLab 2.8 Features
Improved accuracy of generated current dipoles.
Support for conducting simulations on rectangular blocks of cells with=
torso=20
modelling.
Improved accuracy in compound shape modeller.
New cell display modalities, including instantaneous activation wavefr=
ont.
VCG simulation using the Frank or McFee lead systems.
Expanded ElectroWorld viewer windows, incorporating VCG distortion
viewer and=20
selectable regional dipoles.
Heart dipole graph windows.
Automatically calibrated color keys.
New polyhedron editor facet display modalities.
Optional overlaying of traces in ECG, VCG, heart dipole scope, and hea=
rt=20
dipole graph windows.
Bugs Fixed Since Last Release (2.4b0)
Bug 4: Deflections of lead V1 much greater than those of V6.
Bug 5: Heart dipole displays lack of continuity between adjacent sampl=
es.
Bug 11: If cell size is changed after running a simulation, no more=20
simulations can be run.
Bug 13: If a cardiac cycle is run, and resolution is changed, ECG is f=
lat on=20
successive runs.
Bug 24: Wilson=B9s central terminal is assumed to be always zero in EC=
G.
Bug 47: Cell set viewer cutaway offset sliders won't allow the user to=
thumb=20
all the way to the end of their range.
Bug 136: User interface does not perform enough validation of user inp=
ut.
Bug 160: Command-. does not abort the current operation cleanly in all=
cases.
Bug 177: Need to clear ECG window before beginning each cardiac cycle.
Bug 180: Fencepost deletion sometimes deletes the wrong fencepost when
the two=20
are very closely spaced.
Bug 193: Regional dipole locations are drawn incorrectly after restore=

file.
Bug 194: ECG traces are too close together.
Bug 383: Formula for computing ellipsoidal conduction velocities incor=
rect.
