Version: 2x90.5 (Bug-fix Release)

Release date: 09-Apr-2019

!!! PATCHMASTER version 2x90.5 cannot open or export the old PULSE / POTPULSE data files any more. !!!

Conceptional Modifications:

New Features:

Analysis Window

• Analysis Functions
When selecting an Analysis Function in the Analysis dialog, the corresponding cursor pair is shown in the Oscilloscope Window.

Replay Menu

• Marker Export to Igor Format
When exporting traces to Igor Pro, corresponding markers are now exported as "Tags" with the traces.

Photometry/Imaging

• New Calibration Mode
A new (linear) calibration mode was added to for "TILL Photonics"-like light sources (for converting volts to nm and vice versa).

Fixed Bugs:

Analysis Window

• Cursor Bounds Setting
The option "Cursor Bounds %" in the Analysis dialog could only be changed in 10 % steps by dragging. Fixed in v2x90.5.

Protocol Editor

• Set Value Event
The "SetValue" command returned wrong results if it was used for retrieving amplifier parameters. Fixed in v2x90.5.

I/O Control Window

• Digital Inputs

Known Bugs:

None

Version: 2x90.4 (Bug-fix Release)

Release date: 30-Oct-2018

!!! PATCHMASTER version 2x90.4 cannot open or export the old PULSE / POTPULSE data files any more. !!!

Conceptional Modifications:

New Features:

Analysis

• Units of Analysis Functions
Most Analysis functions inherit the unit of the result from the analyzed trace. For example, the Mean analysis function returns a value in [A] if a current trace is analyzed and the unit is [V] for voltage traces. However, some analysis functions (e.g. Math functions) are not Trace-based. In previous PATCHMASTER versions, those results were shown without any unit. PATCHMASTER 2x90.4 allows for manually entering a unit for these functions.

ElProScan

• New Scan Modes
The Scan Modes "Pullup Scan", "Depth Scan" and "ZTrack 3D" were implemented.
• New Export Function
The new export functions to IGOR "3D Scan Export" and "Matrix Export" were implemented.
• Deconvolution Function
A Deconvolution function was implemented.
• Break Scan
Running scans can now be aborted via the "Break" button in the Control Window.
• Focus Motor Axis (FF) option was added to the ElProScan event in the Protocol Editor.
Running scans can now be aborted via the "Break" button in the Control Window.

Fixed Bugs:

Control Window

• Fixed Protocols
In the default configuration only 6 protocols are shown at the same time in the Control Window dialog. If one needs direct access to more than 6 protocols, one can display up to 5 additional rows of Protocol buttons in the Control Window dialog. Protocols then can be assigned to these buttons. In previous versions, no protocol could be assigned to the last of these buttons. Fixed in v2x90.4.

Data Tree

• Converting Data Files from older PATCHMASTER versions
Starting with PATCHMASTER 2x90.3 the data file format was changed in order to be compatible with our PATCHMASTER NEXT software. Data files recorded with older versions need to be converted to this new file format. This is done automatically when opening the file in PATCHMASTER 2x90.3 or 2x90.4. Before converting the file, a backup is created. If such a backup file already existed, the the same file could not be converted a second time. The current version allows converting the file even if a backup file already exists. Fixed in v2x90.4.

I/O Control Window

• Digital Inputs
The Digital Input item was only updated while a PGF acquisition was running. Fixed in v2x90.4.

Known Bugs:

None

Version: 2x90.3 (Bug-fix Release)

Release date: 19-Mar-2018

!!! PATCHMASTER version 2x90.3 cannot open or export the old PULSE / POTPULSE data files any more. !!!

Conceptional Modifications:

File Format

• Version Number
The File Format Version number was changed from "9" to "1000" to make it compatible with PATCHMASTER NEXT.
• Amplifier Settings
The amplifier settings are now always stored in a separate "*.amp" file (which is part of the DAT bundle file). In previous versions, such a separate file was created only for EPC/n amplifiers. It is now possible to open such a data file in "Open Modify" mode regardless if a single amplifier or a EPC/n amplifier is used. Upon opening an older PATCHMASTER data file, this file is automatically converted to the new file format (a backup is created before converting the file).

Configuration

• Window Scaling
The Windows Scaling option was removed.
• Batch Communication
The Batch Communication Mode cannot be changed while SmartLUX or DocuLUX is active. This prevents user from accidentally deactivating the Batch Communication.

Amplifier Window

• CC-Gain Default Setting
The default setting for CC-Gain was changed from 0.1 pA/mV to 1 pA/mV.

Photometry / Imaging

• Device List
The entry "TILL Photonics" was renamed to "TILL Photonics / Cairn OptoScan".

Pulse Generator

• "Load from File Template"
When selecting "Load From File Template" the "DA-Scaling" and "StimScale" option are turned "Off" for this channel.
• Photometry / Imaging Traces
The input trace labels for Photometry and Imaging have been renamed: "Photometry Wave" to "Photometry" and "Imaging Wave" to "Imaging".
• "Use for Camera Trigger"
If "Use for Camera Trigger" is selected for the output channel then the channel timing for this channel is set to "Separate Timing".
• Continuous Acquisition
Under certain conditions, a Zero Subtraction cannot be performed online. Under these conditions, the message "Conditions not met for continuous acquisition" was written to the Notebook window and the Zero Subtraction (Display menu) was permanently turned off. The Zero Subtraction is now only disabled for this acquisition but is NOT turned off in the Display menu.
• Gap Free Mode
The number of sweeps is now limited to "1" in the Gap Free Mode if the channel uses a "Continuous" Segment Class.

Protocol Editor

• "Set Digital Bit" Event
The label of the check box toggled between "low" and "high". This label is now always fixed to "Checked = HIGH".

Replay Tree

• Text/Label Data
The "Text" or "Label" buttons to enter or rename labels in the Replay Tree are now automatically enabled or disabled depending on the selected data tree level.

Replay Menu

• Export
Export options are now only displayed if the export options are really available.
Line Feed and Carriage Return options were removed from the ASCII Text Format menu (CR, CR-LF, LF Only).
The option "IGOR Info File" was removed.

SmartLUX

• Area of Interest (AOI)
The function to select the read-out rows of the image was added which allows now to support the AOI feature of modern scientific cameras. Especially for Rolling Shutter cameras, the readout time depends on the number of rows to read from the sensor. Reducing the number of rows can increase the frame rate.
• Binning Modes
The number of available Binning modes (and the corresponding labels) is now transfered from SmartLUX to PATCHMASTER and listed in the Imaging Parameters dialog of the Pulse Generator.

Protocol Editor

• DocuLUX Event
The DocuLUX Event was added to the Event pool.
• "IF...THEN" Event
For the Break Alert source the user can now define labels for the two options "Break" and "Continue".

The list of Camera Trigger outputs (DA / Dig output channel) was mixed up. Fixed in v2x90.3.

Pulse Generator

• Segment Classes
It was possible to set the Segment Classes "Chirp", "Sine", "Square" and "Ramp" in combination with digital output channels. This is now disabled. Fixed in v2x90.3.
• Moving PGF Sequences
After moving PGF sequences the focus (selection) did not move along with the moved PGF sequence. Fixed in v2x90.3.
• Sample Interval
The calculation of the minimum sample interval was not always computed correctly for a given number and/or combination of AD inputs when using an EPC 10 USB amplifier or an LIH 8+8, particularly if 2 units were used. Fixed in v2x90.3.
• Gap Free Mode
When using the Gap Free Mode in a stimulation sequence it could happen that the temporary stimulus file created by PATCHMASTER exceeded the 2 GB limitation which ended in a crash of PATCHMASTER. This is now checked before the temporary stimulation file is created and in case of need this gets prevented. Fixed in v2x90.3.
• HT-Templates
The HT-Template function did not work. Fixed in v2x90.3.
• Checking Routine
When creating invalid stimulation sequences PATCHMASTER complained that there are multiple errors and further asked if you want to disable the checking. If you left the Pulse Generator window in that condition PATCHMASTER went into an infinite loop. Fixed in v2x90.3.
• Digital Outputs
After executing a stimulation sequence with several sweeps a digital line that was used in that sequence was set to "High" after each sweep. Fixed in v2x90.3.

Protocol Editor

• "Export" Event
The "Filename" field of the Export event was ignored. Fixed in v2x90.3.

Analysis Window

• "Cursors: Copy from function"
Selecting a new "Cursor Source" for an Analysis function had no effect. Only after changing the cursor range of the new source function, the range of the target function was updated. Fixed in v2x90.3.
• Analysis Functions in Multichannel Mode
Copying an Analysis Method containing 2 Analysis functions (and 4 Amplifiers) resulted in a new Analysis Method with 8 Analysis functions. Fixed in v2x90.3.
• Grid Color of Analysis Graphs
Under certain circumstances it happened that the grid color of the Analysis Graphs adopted the color of the trace. Fixed in v2x90.3.
• Loading Analysis Files
If a data file is open in "Modify" mode and one loads an "*.onl" file PATCHMASTER crashed upon updating/closing the data file. Fixed in v2x90.3.
• "Threshold Crossing" Function
When setting the "Threshold Crossing" function to "Positive Crossings" and the threshold to a negative value PATCHMASTER crashed while replaying data. Fixed in v2x90.3.
• "Adapt to Position of Function" Function
Using "Adapt to Position of Function" caused conflicts in Cursor adjustment. Fixed in v2x90.3.
• Cursor Bounds and Segment Offset
The selected "Cursor Bounds" were not applied if one used it in conjunction with the Segment Offset function. Fixed in v2x90.3.

Markers

• File Bundling when using Markers
After acquiring data with Markers and unbundling the file afterwards the Marker file was not read any more. Also when bundling the file again the information from the marker file seemed to be lost. Fixed in v2x90.3.
