ScanImage

3.5

introduces some changes to the way INI files are handled. Please familiarize yourself with the section about [Initialization (INI) File Handling].{info} A subset of the INI file variables -- termed the *Rig Configuration* variables -- are demarcated at the beginning of the INI file. Rig Configuration variables are those which may require modification for a new ScanImage installation. These variables are rig-specific, and are not associated with either configuration (CFG) or user (USR) files. The values for these variables are not modified/modifiable during ScanImage program operation. h5. Rig Configuration Variable Reference This section serves as a reference to the new and notable _Rig Configuration_ variables in ScanImage 3.5. {report-link:source=ScanImage Files^r3_5_standardINI_rigConfig.txt|key=attachment:download path|target="_blank"}*View Rig Configuration section of _standard\_model.ini_ file*{report-link}. Users should adjust the Rig Configuration values to match the hardware and experimental requirements for their rig, creating their own _standard.ini_ file.

These variables are unique among the Rig Configuration variables in that they can be altered during ScanImage operation. See [Beam and Scan Alignment Tools] for more details. *parkAmplitudeX/Y*: (Previously below Rig Configuration section) Specify voltages determining X/Y mirror positions when parked. (!) Beam safety should be considered in setting these values. *maxAmplitudeX/Y*: Specify max voltage allowed for X/Y amplitudes. This clamps the sum of the scan amplitude and the scan shift set in ScanImage, for each dimension. h6. Shutter Variables The separate values for 'open' and 'closed' have been removed. Variables _open_ and _epiShutterOpen_ are sufficient to specify the 'polarity' of shutter TTL control signal. The variable _shutterBoardIndex_ is new in r3.5. See [Shutter output line(s) can be on any board]. h6. Motor Variables The number of variables in the rig-specific motor section has been greatly reduced. Two variables, _firmware_ and _posnResolution_, are new in r3.5. See [MP-285 Interface Improvements] for more details. {panel}

changes somewhat the way the INI file is loaded at startup. This is described in the section about Initialization (INI) File Handling.

A subset of the INI file variables – termed the Rig Configuration variables – are demarcated at the beginning of the INI file. Rig Configuration variables are those which may require modification for a new ScanImage installation. These variables are rig-specific, and are not associated with either configuration (CFG) or user (USR) files. The values for these variables are not modified/modifiable during ScanImage program operation.

Rig Configuration Variable Reference

This section serves as a reference to the new and notable Rig Configuration variables in ScanImage 3.5.

Center

Users should adjust the Rig Configuration values to match the hardware and experimental requirements for their rig, creating their own standard.ini file.

(tick) The standard_model.ini file contains comments which document the meaning of each of the variables.

Panel
titleNew/Notable Variables in _standard_model.INI_

triggerLineIndex: (Previously below Rig Configuration section) Allows specification of the static digital output line used as the shared trigger source for acquisition, mirror, and Pockels cell board(s). The use of Port 0 on the board specified by triggerBoardIndex is assumed.

triggerInputTerminal, externalTriggerInputTerminal, externalTriggerTimeout: See the sections on Triggering Simplification and External Triggering for more details.

outputBoardClockTerminal: See Clock Synchronization for more details.

maxBufferedGrabTime: See Unlimited and Uninterrupted Acquisition for more details.

scanOffsetX/Y: (Previously below Rig Configuration section) Specify offset voltages for mirror command signals, i.e. the center of the laser scan. These variables are unique among the Rig Configuration variables in that they can be altered during ScanImage operation. See Beam and Scan Alignment Tools for more details.

parkAmplitudeX/Y: (Previously below Rig Configuration section) Specify voltages determining X/Y mirror positions when parked (i.e. when no acquisition is occurring).
(warning) Beam safety should be considered in setting these values.
(tick) When the beam is parked, the shutter is closed and the Pockels Cell set to minimum transmission.

Shutter Variables
  • Variable shutterBoardIndex is new in ScanImage 3.5.
  • Several variables (e.g. closed, epiShutterOpen, and epiShutterClosed) have been removed.

(tick) See Enhanced Shutter Configuration for more details.

Motor (MP-285) Variables
  • Variables umPerStepX/Y/Z have been added, replacing calibrationX/Y/Z values in ScanImage 3.0.
  • Variable posnResolution is also new in ScanImage 3.5.

(tick) See MP-285 Interface Improvements for more details.
