ScanImage 3.5
About Current and Upcoming Releases
This new release has been developed primarily to support ScanImage users who no longer have ready access to the older Matlab version for which earlier ScanImage releases had been developed. It is also ScanImage 3.5 is known to be compatible with Matlab 2007b. In addition, it is now compatible with the newer National Instruments driver (DAQmx), which many users may prefer to install instead of the older drivers ('rather than the Traditional NI-DAQ '). It is anticipated that this version will remain compatible with current and upcoming Matlab versions.driver required by earlier ScanImage releases.
ScanImage 3.5 is very similar to 3.0 and new users may want to refer to the ScanImage r3.0 Documentation to become familiar with this software.
Changes
However, some important changes have been made. New and returning users should familiarize themselves with the documentation of the Important Changes in ScanImage 3.5. Notably:
- The Selection Dialog no longer appears at startup
- The handling of the INI file, which must be created by the user, has changed somewhat.
- The board wiring required for trigger and clock synchronization has been modified
- The Main Controls window has several modifications
New Features
In addition to these changes, several In addition, a handful of new features have been added to ScanImage 3.5 to help support ongoing experiments by ScanImage users at HHMI/Janelia Farm Research Campus.
Plans are underway to significantly rewrite ScanImage from the ground-up, in order to better support a growing number of laser scanning devices and applications. In addition, ScanImage will become integrated with the Ephus project, in order to allow for consistent conventions for file saving, configuration switching, and other crucial components of a general-purpose neurophysiology data acquisition software package.
We welcome feedback on ScanImage 3.5 and certainly will address any critical deficiencies that may be identified. Please note that any significant requests are more likely to be incorporated into plans for the new ScanImage package.
New Feature Summary
These and other Important New Features in ScanImage 3.5 are described fully in the documentation:
- Live
- Compatibility with current Matlab/National Instruments releases (R2007B/DAQmx 8.6)
- Real-time RGB channel 'merge' display during Focus mode
- Disk-logging Grab/Loop acquisitions
- 'Infinite' focus modeUnlimited & uninterrupted acquisitions via TIF streaming-to-disk
- Ability to accept external trigger (, using separate trigger input terminal ; (e.g. facilitates Ephus-driven acquisitions)
- 'Bidirectional' scan capability, enabling fast <1ms/line scans
- Command-line utility functions for commonly-needed tasks, including beam-parking and 'cusp'-delay optimization
- Enhanced MP-285 interface and configuration
- Improved support for case of 3 'beams' (i.e. 3 Pockels Cells)
- Tools to facilitate beam and scan alignment
- Enhanced Extended 'hot-key' functionality to support rapid program control and configuration switching
Bug Fixes
A handful of bugs identified in ScanImage 3.0 have been addressed in this release.
