What's new in WinLTP 2.30 - 2.32

 

1) Create a new AnalysesToDo dialog box,  Separately analyse S0 and S1 detections

In WinLTP 2.30 and earlier versions, the AnalysesToDo dialog could only chose to analyse, or not analyse, S0 and S1 detections together (Figs. 3 and 4).  Furthermore, there were separate columns columns for MainPg and AnalysisPg in the AnalysisToDo dialog box.  This makes many unwanted analyses that result in 0.000 values in Fig 4 (see red arrows).

 In WinLTP 2.31 the AnalysesToDo dialog you can now choose to separately analyse S0 and/or S1 detections (Fig. 5 and 6).  Now, whether the plot appears on the MainPg, the AnalysisPg or both pages depends on whether an ‘M’, ‘A’ or ‘B’ is entered.  Note that Fig. 6 shows that only the detections desired have been printed to the spreadsheet, and the rows in Fig. 4 that only contain 0.000 values are no longer printed.

And if spreadsheet AmpSlope value is not to be calculated, ie "", then a 0.000 data point will not be plotted in the Analysis Graph (Figs. 4 and 6).

 

Fig. 3.  The OLD WinLTP 2.30 and earlier AnalysesToDo dialog choosing to analyse S0 and S1 Peak Amplitude on AD0, and S0 and S1 Slope on AD1.  This has columns for MainPg and AnalysisPg.

  

Fig. 4.  WinLTP 2.30 and earlier - choosing to analyse S0 and S1 Peak Amplitude on AD0, and S0 and S1 Slope on AD1.  This makes many unwanted analyses that result in 0.000 values as shown in calculation row #’s 3 and 4, and 5 and 6 (see red arrows).

 

Fig. 5.  The NEW WinLTP 2.31 AnalysesToDo dialog choosing to analyse S0 Peak Amplitude on AD0, and S1 Slope on AD1.  Whether the plot appears on the MainPg, the AnalysisPg or both depends on whether an ‘M’, ‘A’ or ‘B’ is entered.

 

Fig. 6.  WinLTP 2.31, analysing only the S0 Peak Amplitude on AD0, and the S1 Slope on AD1.  Note that there are no extra rows with only 0.000’s, and no extra 0.000 points plotted in the Analysis graphs.

3) Separate Filename Extension Column in Saved Spreadsheet

WinLTP 2.31 has added a separate 'Filename only ' and 'Filename Ext' columns to Excel XLS spreadsheet and ASCII Amp files to enable easier sorting by filename and/or extension.  This will enable easier sorting by the "P0", "AP1" etc filename extensions.

 

 

4) ‘Dynamic allocation of stimulation and detection fields to conserve Windows resources

The S0, S1, IC0 and IC1 stimulation fields are now ‘dynamically allocated’.  This means that rather than having these four groups of fields all allocated at program startup, only the one current S0, S1, IC0 or IC1 group of fields will be allocated.  Furthermore, the AD0 a nd AD1 channel detection fields are also now similarly ‘dynamically allocated’. 

This results in a massive saving of Windows resources (specifically the “User objects” shown in the Task Manager of which WinLTP is a bit piggy).  This will allow WinLTP 3.00, to increase the extracellular stimulation outputs from 2 (S0 -> S1) to 8 (S0 -> S7).  And it allows WinLTP to increase the detection fields for AD channels and extracellular stimulation from 4 (AD0 -> AD1 times S0 -> S1) to 48 (AD0 -> AD5 times S0 -> S7).

However, in this version you will probably not notice the difference.  This is an internal change. 

 

You WILL have to rewrite your protocol files when upgrading from WinLTP from 2.30 or earlier.

 

 

What's new in WinLTP 2.30

5) Fully Compliant with Windows 10

WinLTP 2.30 is primarily a major compiler upgrade to make WinLTP completely compatible with Windows 10.  For example, the file system will now work perfectly on Windows 10. However, most of the changes are internal, "under the hood" and are not apparent to the user.

WinLTP 2.30 will run on Windows 10, 8, 7 and Vista, but unfortunately will no longer run on the obsolete Windows XP. While it makes sense for a data acquisition program like WinLTP to run on a Windows XP computer NOT connected to the Internet, most computers must be connected to the Internet. Because Microsoft no longer supports Windows XP, Windows XP computers cannot be connected to the Internet. It therefore makes sense that our latest Embarcadero/Borland C++ compiler no longer supports Windows XP.

Therefore in addition to providing WinLTP 2.30 that runs on Windows 10, 8, 7 and Vista, we will continue to provide Windows 2.20 to run on Windows 8, 7, Vista and XP.

NOTE: For Windows 10 and the M/X-series boards, you should use NI-DAQmx version of 15.5 or later.
