LabChart Support

General

• The LabChart file format has been updated. As such, .adicht and .adiset files created with LabChart 8.1 cannot be opened in previous versions of the software.
• Improved drawing of check boxes in the Input Amplifier dialog.
• When importing text files in LabChart for Mac, it is now possible for the user to specify a value for the default sampling rate.
• Improved performance when opening files without PowerLabs attached.

Channel Calculations

• Cyclic Measurements event channel calculations now consistently draw out to the last event while sampling.
• Improved scrolling performance in channel calculations.

Export

‘Use simple format’ can now be used in Export MATLAB.

Stimulator

Users can now specify very narrow stimulator pulses.

Data Pad

Various improvements have been made to editing formulae and entering data in the Data Pad.

Welcome Center

Improvements have been made to the Welcome Centre functionality to better support the Experiments folder.

General

• Added support for new generation Octal and Quad Bioamps.
• Added ‘synchrony’ arithmetic expression for showing synchronization between two event channels.
• Fixed a bug where arithmetic expressions using another channel’s raw data weren’t always being loaded properly from settings files.

Upgrading from a non-English version of LabChart using Feature Manager now installs the correct language version.

The DMT Device Enabler now initializes correctly from LabChart.

General

Added support for the Spirometry 2.5 Extension.

General

• General user interface and stability improvements.
• Improved stability of modules when analyzing while sampling.

Chart and Scope View

• Improved responsiveness of the Movie View marker.
• Reinstated the ability to make a selection when sampling.
• Reinstated Scope macro commands.

Import

Reinstated the ability to selectively import channels from EDF files.

General

LabChart is now fully compatible with Windows 10 Anniversary Update.

Windows

• LabChart 8.1 or later do not support Windows Classic theme.
• In the Preset Comment "Event Configuration" dialog, if "Comment only on first stimulus" is checked, the comment is disabled for the entire record after the first pulse.

Mac

• If you are on OS X v10.11 (El Capitan) and have already upgraded to LabChart 8.1.2 - Please upgrade to 8.1.3 here on our website rather than in feature manager. You can then proceed as normal for all future upgrades.
• There are some features that were present in LabChart 7 that are not currently included in LabChart v8.1. Click here for more information.
• The ADInstruments Blood Flow Meter is occasionally initialized with only one channel enabled. The user can manually enable the second channel.
• For machines that have high-resolution Retina displays, users may encounter responsiveness and stability issues when using the Scope View.

Mac and Windows

General

• While recording, comments can now be moved without issue.
• Arithmetic variables can now be used in Arithmetic channel calculations on systems that use European region localisation.
• Fixed an issue where Scope pages names were forgotten in certain saved files.
• Fixed issue where the Stimulator could produce an extra half cycle beyond the number of cycles requested, at some frequencies, such as 500 Hz.
• In order to assist with data recovery in situations where a saved data file is lost or damaged, a fixed number of the most recently recorded data files are now retained as backup.
• Fixed an issue affecting documents recovered via disk buffer recovery. LabChart now prompts the user to save the file when LabChart is closed.

Windows

General

• Fixed several instances of incorrect wording relating to the Spectrum feature with Japanese and Chinese versions of LabChart.
• While recording, Scope in comment mode now updates immediately to show the correct list of pages each time a comment is deleted.
• The list of recently opened files in the Welcome Center and File menu now updates immediately when a file is closed.
• Fixed an issue preventing use of milliseconds as the time unit for Max Repeat Rate within the Stimulator panel if the Isolated Stimulator is being used.
• The Isolated Stimulator Current parameter can now be adjusted in increments that are multiples of 0.1 mA. Previously, it was limited to being multiples of 0.2.
• Fixed a LabChart stability issue when increasing channel count and applying channel calculations from within the Channel Settings dialog.
• Fixed a usability issue affecting renaming Scope pages.

Improvements

• A new "File Name" Data Pad function is available under the Block Information section in the Data Pad Column Setup Dialog which returns the name of the file containing the current selection.

Mac

General

• The data scale in the Input Amplifier dialog now correctly adjusts as the hardware range is changed.
• Fixed an issue when entering a fixed duration in milliseconds within the Sampling Dialog.
• When modifying an existing units conversion, LabChart now always looks at the underlying raw data.
