=Easy Upgrade

}To upgrade from ScanImage 3.7.0, you can use use your existing INI/CFG/USR files! (To upgrade from earlier versions, new INI/CFG/USR files should be created.)

{tip}

h4. Enhancements
* Support for PXI-based DAQ boards (e.g. PXIe-6124) & USB X series boards (USB-6356)

* Allow scan angular range values up to 40 optical degrees

* Support input channel voltage ranges of 0.2, 0.5, and 20V

* Smarter beam parking to avoid large step transients on scan start

* Configurable delay for motor steps, to allow for motor 'settling' before starting next slice in a stack

* Configurable delay for shutter opening, to allow for shutter 'settling' before starting acquisition

* Support for slower line periods of 16-128ms

* Support small frame sizes (e.g. < 32 lines) without generating TIF errors

* Support for negative photodiode voltages

* 4-digit display for countdown/timer

h4. Bugfixes
* Motor operation reliability issues eliminated, or greatly reduced
* Image data collected with Snapshot would disappear
* Scans driven by ROI/LS/CT selections were incorrectly positioned

* Change to fill fraction during FOCUS was producing error

* Scan delay values were corrupted switching between bidirectional and sawtooth scanning

* Power was being set incorrectly at end of P/z stacks when _Return Home After Acq/Repeat_ is disabled

* Pockels calibration now works in rejected-light case

* _# Frames/File_ adjustment now accounts for _# Z Slices_ and _Average Frames_ settings correctly

* _Zero XY_ and _Zero Z_ operations no longer act like _Zero XYZ

_
* Recent _Zoom_ and other scan setting changes are now correctly honored at start of LOOP acquisitions
* TIF files where linesPerFrame is not a power-of-two are now correctly read by ImageJ

* Discontinuous slow-dimension scan command waveform fixed, for case where _Flyback on final line_ is selected

* Hard error no longer occurs after some bad Pockels calibrations

* Fix support for Matlab 2009b, which was broken for case where exported clocks are used

* In User Functions dialog, edit operations could affect the wrong event, inadvertently

* Save selections in *Channels...* dialog were being ignored

* Crosshair was appearing doubled on ScanImage startup

* _Override Lz_ was being applied even when start/end-points were not defined

* Error indicating insufficient buffering could occur when using slower imaging rates and with _Disable Image Striping

_ enabled
* _scim\_openTif()_: error was occurring for cases when channels selected for saving are not contiguous

 
* Sporadic errors occurring during PMT Offset determination fixed

* Position was not correctly displayed at end of Zero XY/Z/XYZ operations; now motor position is read before setting zero

* Some header values were not saved correctly when Pockels cell feature was

 disabled
