8.02 |
New
- Added Meas() function to the virtual channel system.
- Multiple frames uses Save changes dialog with stop button.
- Auxiliary states device settings are now saved in experimenter's notebook.
- Frame tagging, show buffer, frame overdrawing and changing the current frame can now be undone.
- Deleting cursors (vertical and horizontal) can now be undone.
- Info windows can now display state labels.
- Signal now attempts to prevent a user logging off or shutting down while sampling is in progress.
- Conditioner controls can now be accessed while sampling for multiple conditioners.
- It is now possible to drag attachments from an email in Outlook directly onto Signal, to have it open them. The files are copied to a folder in Downloads called Outlook (or Outlook(n) if a folder already exists there of that name).
- It is now possible to specify lists of states where a frame list would previously only allow one state.
- A new type of pulse item for additional actions has been added to the pulses dialog. Currently this only supports turning dynamic clamping models on or off.
- Pulse dialog now indicates the X zero position in the sampled data with a z below the control track.
- SampleStatus() has been enhanced to allow more detailed information about the status to be obtained.
- An error message is now given if a talker fails to run.
- Talker channels can now be duplicated in the sampling configuration.
- A warning is now given if you attempt to set up more than one conditioner on a given port.
- Adding channels from multiple talkers is now possible.
Fixes
- Dragging a pulse when using very fine timing resolution could fail to draw the new pulse location correctly during the drag.
- Can now change input for 1902 and have updated gain list online.
- Talker data could be missing after restarting sampling.
- PulseWaveSet() will truncate the number of waveform points if it would exceed the available 1401 memory when being used online.
- Arbitrary waveform points and DACs cannot be changed online.
- SampleStatus() could return incorrect information when used in a triggered script.
- Drift compensation strings have been corrected for talkers.
- Talker channels are now always listed correctly.
- Some USB/RS232 adaptors would fail to enter themselves into the registry and thus be excluded from the com port lists. Signal now checks for this and includes them with a basic COMn name.
- You can no longer drop files onto Signal when the File menu is unavailable.
- Triggered scripts were being run too early.
- Restarting sampling could, on some computers using a long USB cable, sometimes cause the 1401 device driver to unload and Signal to stop working.
- Closing the D360R control dialog while sampling could crash Signal.
- If a conditioner control dialog failed to open for any reason while sampling, the menu options to open any conditioner would be greyed out for the remainder of the sample run.
- It would sometimes take two attempts to close a conditioner control dialog while sampling.
- You can now import Intan rhd files that contain temperature sensor data.
- Protection has been added to prevent arbitrary waveforms being defined that would use more than the available space in the 1401 to store them.
- The 1902 setup dialog now initialises correctly when there is no configuration file.
- When using the D360R with a port offset applied, changes made by Digitimer software are reflected in Signal dialog.
- The SampleStop() script command now returns correct error codes if it fails for any reason.
- Tooltips now work again in script views.
- Previously, the automatic MEP detection mechanism available as part of the MTAT threshold measurement system would usually give incorrect results due to it analysing the wrong channel. This has now been fixed.
Changes
- When using the D360R conditioner setup with no configuration file, the dialog is populated with the current settings of the conditioner rather than default settings being used to change the conditioner.

8.01 |
New
- A new peri-trigger mode has been added for remaining inside a pair of levels for a specified time.
- A new script command, SamplePeriDwell() has been added to allow the dwell time for the new peri-trigger mode to be set.
- It is now possible to use more than one signal conditioner at a time; e.g. the CED 1902 and Digitimer D360R can both be used simultaneously.
- Units have been added to the threshold items in the peri-trigger page.
- Utility programs can now be run from the File menu.
Fixes
- Virtual channels now cope with frames of different lengths.
- More time is now allowed for switching from monophasic to biphasic pulses with a MagPro.
- COM ports of number greater than 9 can now be used for conditioner control, auxiliary states devices and when opened from a script.
- The space occupied by the Wait/Trigger check box in the sampling control panel has been increased to avoid truncated text in some circumstances.
- You can now drag the hysteresis cursor if the hysteresis is initially zero when doing downward crossing peri-trigger.
- Calling ChanfitCoef() for a non-existent XY channel no longer crashes Signal.
- COM ports are no longer left open after loading the signal conditioner dlls. This could cause problems when changing conditioner type or trying to use the port for something else.
- The MTAT RMT message given at the end of the process could be lost behind the application window. This is no longer the case.
- The Channel Information dialog now allows the full 20 characters for a title and 8 characters for units.
- Now correctly ignores the interlock switch on a Magstim Rapid2.
- Magstim Rapid2 no longer disarms before the trigger is sent when it has new firmware.
- Cursor(0) no longer appears in active mode dialogs for cursors in XY views.
- Extended markers in non-native files now import as markers correctly.
- Signal no longer crashes after importing smr files.
- You can no longer access the pulses dialog from auxiliary device dialogs when not in pulses mode. This was causing confusion as the pulses defined here are not used unless in pulses mode.
- In user defined dialogs generated from a script, focus would be set to the first control when there was a default button but no fields (so focus ended up on first button and not on the default one). In a dialog with only buttons, focus is not on the default button when the dialog is displayed.
- Signal now recognises if a talker fails and tidies up so that the next connection attempt succeeds.
- Signal could sometimes crash if active cursors were being used online and were feature-searching a talker channel.
- Clicking on Finish twice at the end of sampling could leave Signal in a confused state. Clicking once now immediately disables to button.
- The list of configuration files in the Load configuration menu item is now greyed while sampling.
- Both the experimenter's notebook and the talker information were showing the drift as a value in s/s, but the units were shown as ms/s (which was what was wanted and what we see now).
- It is now possible to make changes to the D360R settings while sampling. Previously changes would be lost when attempting to apply them.
- The Sample bar menu item is now greyed out when there are no buttons to display and the bar is hidden.
- Data could be lost from the start of a talker channel if the frame started too soon after the previous one.
- Pre-trigger talker data is now drawn correctly in peri-trigger mode after adjusting the trigger levels.
- The number of pre-trigger points used for peri-triggered sampling will now automatically reduce if the total number of points is set to less than the pre-trigger points.
- Closing a sampling window while sampling a talker channel non longer crashes Signal.
- Errors in the ADC port list in the General tab of the Sampling Configuration dialog are now only reported once per edit.
- An error is now generated if you attempt to sample markers when the outputs resolution and sweep length are such that they could be lost.
Changes
- The error level for a log message warning of a power level not being set on a MagPro has been reduced to INFO as it was quite common and worked on an automatic retry.

New
- Signal can now collect data from talkers, separate programs which manage alternative data acquisition devices and can supply data sampled from these devices to a host program.

- The SampleStart() script function now obeys the start on E1 flag in the sampling configuration unless it is used to force an E1 start.
- The deferred online optimisation preferences option now only takes effect if data is currently being sampled. Optimisation during the intervals between sampling sweeps will take effect immediately.
