- The random channel list parameter is now parsed as a list first, and taken as
a file name only if it doesn't make sense as a channel list. It used to be
taken as a file name first which caused problems when you had files whose
name was just a number.
- QNX version of capture programs now allow 31 channels in list, which is the
largest list the WIN-30D can support. This limit is now checked during
- Extra numbers that were used to pad the channel list and divisor lists are
now stripped out when the channel table is edited. Previously, these sometimes
remained and caused problems later on.
- New trace or waveform entries can now be quickly inserted into the channel
table with a double click.
Channel table error checking was also improved, and repeated channels are
now handled much better.
- Trace amplitude graphs that use the integration option now show the
scale of results correctly as a product of voltage and time. Prior to
this fix (Aug. 27/98) trace amplitude graphs scaled the data incorrectly
when using the integration option. The values displayed were too large, by
a factor of how many points were used in the integration. E.g. if your
sample window included 23 data points to be integrated, the displayed
result was 23 times too large.
- Requesting help, with "?" key, at "Go" menu item now shows description
of selected analysis method, or "Initial actions" page if none selected.
- At the main menu, pressing the "<" or ">" key now turns on the Cursors
display option and runs the analysis, to quickly get cursor readings.
- Manual cycle selection now avoids any pairs of markers previously set
outside of the current analysis range. These used to cause problems.
- Improvements were made to manual selection of single-unit spikes
to better handle spikes outside of the current analysis range.
- Saving deleted section information in analysis parameters now works correctly
on QNX and Linux. A byte-ordering problem used to cause the analysis program
to crash or fail to save the deleted sections.
- There is a new "Overlay-W.F." option to get two waveforms superimposed during
waveform parameter setting, to aid in setting times.
The waveform selected by this parameter will be shown
using the marker colour, while the waveform for which you are setting
waveform parameters will appear in the usual axes colour.
- A View/Required operation for the Raw W.F. display analysis now shows the
cycle parameters when the Display crossings or Display cycle length option
- The Raw W.F. display analysis now properly shows deleted sections that
are partially outside of the analysis range.
- Fixed a buffer overflow problem in the raster program that was caused by
long lines in the
file. These should no longer cause the program to crash.
- Marker settings in the raster program now work correctly on QNX and
- The peel program now makes markers smaller after they're set, and uses
different sizes for markers in the first and second peel, to clearly
- On X Window displays, the peel program now plots data points using a small
diamond symbol, rather than a single dot, for better visibility.
- The axon2run program now handles episodes larger than 16K samples.
It also now allows
file name extensions, as well as
(in lower or upper case) and avoids invalid file comments (strings of
control characters) which occur in some files.
This program still does not fully support the newer Axon Instruments ABF
file format, so if you can still save down to their DOS binary format
(.dat) that is still preferable.
- A small Y2K bug in the genman program was fixed.
This program now also correctly handles the new date format that recent
versions of GNU tar use.
- Software ported to Red Hat Linux 6.x, using glibc 2.1.
