Here you can download the current version of the HemoLab software:

HemoLab Ver. 10.6 (July 9, 2010) Now Analyzer can do Detrended Fluctuation Analysis (DFA)!

This is the setup file for the HemoLab software. It includes:

• A Data Aquisition software (WinAD) New: AD-Converter for WinAD
• The Analyzer software (Analyzer)
• A Batch Processor (Batch Processor)
• A statistics software (WinStat, Windows port of the Linux program XmStat). The HemoLab software comes with a PDF file of the manual for the WinStat statistics software.

• Minor bug-fixes in WinStat. Related to Wilcoxon Signed-Rank Test and missing values.
• Some minor bug-fixes.
• Added a function to WinAD that shows digital readouts of the recorded values.
• Added a Driver for WinAD that supports an AD converter based on a PIC12F683 microprocessor. Some minor bug fixes.
• Minor changes in WinAD regarding regulator (option to average input values over reset interval).
• Results can now be printed and saved from the results window. No more need to use copy and paste (although this is still possible).
• Added two-variable transformations to WinStat
• Minor bug fix for 2-way ANOVA with repeate/repeated measures.
• Added one-variable transformations to WinStat
• WinStat can now do non-parametric tests (Wilcoxon and Mann-Whitney).
• Batch Processor can now convert FastPicTeX files (generated by WinStat) directly into JPG, TIF, GIF, PS, or PDF files.
• Added graphics (through FastPicTeX and LaTeX) to WinStat. WinStat can now write FastPicTeX files that can be processed with LaTeX. FastPicTeX is now included with HemoLab.
• Finalized ANOVAs (1-way-repeated, 1-way-independent, 2-way-repeated-repeated, 2-way-repeated-inependent, 2-way-independent-independent). Results of the statistical tests have been compared and verified agains a commercial statistics software. The results were identical with the commercial software and with WinStat.
• Added 2-way ANOVA for independent/repeated measures and independent/independent measures. Two-way ANOVA for repeated/repeated is still missing. Also non-parameteric tests are still missing.
• Started a Statistics Program WinStat (for descriptive statistics, t-tests, ANOVAs, etc.)
• Minor bug fix in Analyzer
• Added Heart Rate Variability to Batch Processor.
• Added the number of BP ramps (independent from HR ramps) to sequence technique for baroreflex estimation.
• Small fix in WinAD
• Small bug fix related to automatically opening ASCII files that are beat-by-beat data.
• Continued working on beat-by-beat sampled data files. Still needs work.
• Started working on beat-by-beat sampled data files to be used for baroreflex analysis. Not working yet, but getting close ...
• Finalized transfer function support in the Batch Processor.
• Added a regulator module to WinAD. This module is based on a PID regulator and can be used to regulate the recorded parameters. The output of the regulator is via the parallel port or via the DLP-IO8 device.
• Added the transfer function (with overlapping segments) to the Batch Processor.
• Added a stimulator module to WinAD.
• Added a driver for the DLP-IO8 AD-converter. This is a low-cost (<$30) 8-channel AD-converter that connects to the computer via the USB port. Unfortunately, this device is not designed for high-speed data acquisition. With WinAD, the highest sampling rates are in the range of 250 Hz (for one channel) and 80 Hz for all 8 channels simultaneously. The input range is from 0V to 5V. Information is available from:

  The device can be purchased from Mouser Electronics at:

• Added a timer to the data acquisition software WinAD that shows for how long  the recording is running. This information is shown in the status bar at the bottom of the WinAD main window. Also fixed a small bug related to monitor mode.
• Minor bug fix, related to opening files in Analyzer by double clicking on a data file.
• Added myhotpix to the Batch Processor and did some minor bug fixes on the AUC for the spectral analysis.
• The batch processor can now calculate the areas under the curve of the power spectra. Thus, the full power spectral analysis is now available in the batch processor.
• Added a small command line program that makes beat-by-beat data files equidistant (mkequi).
• Added delays to baroreflex (sequence technique) calculations. 
• New time series of the time points of the baroreflex sequences and feed-forward sequences can be generated from the baroreflex results window menu.
• Worked on the Batch Processor. It can now calculate spectra. Areas under the curve for the spectra (to quantify VLF, LF, HF) are still missing.
• Added a driver for WinAD that does not depend on DirectIO. It uses the Windows API functions to access the serial port. This is somewhat slower than direct access via DirectIO. For high sampling rates DirectIO is still recommended. However, for lower sampling rates the Windows API functions are just fine.
• Worked on the baroreflex function. Make it more easy to identify individual sequences. Added standard deviation of gains.
• Minor bug fix.
• Added a routine to the Batch Processor that converts MacIntosh files to the PC format.
• Improved the baroreflex function of the Analyzer software. Now it is very easy to manually exclude "artificial" sequences from the analysis.
• Started working on a Batch Processor that will help to automatically generate the batch files necessary to analyze large number of data files (e.g., all files of a complete study) all at once.
• Worked on the Data Acquisition Software. Specifically, added derived channels (e.g., derive HR, SYS, MEAN, DIA blood pressure online during recording).
• Analyzer can now copy results into the Windows clipboard and then paste them into other programs, such as MS-Excel.
• Started to work on a still rudimentary Help File for Analyzer.
