Customizable Chart Titles and Axis Labels
All titles and labels of graphical reports can be edited when clicking on them. Your text is processed by a TeX interpreter, i.e., you can use ^ for superscripts, _ for subscripts, {} for grouping. Also, special commands for Greek letters (\alpha, \beta, \gamma, \Gamma, …) are available.
Default labels for x- and y-axis can be specified in the report preferences.
New Baseline for Peak Integration
Baseline option Linear Fit - already known from the data pretreatment model - is now also available for integration models. Compare all four options at a glance:
- None: Baseline is zero; integration result may be negative if signal is negative.
- Offset: Baseline is the smallest y-value within x-limits; integration result is positive.
- Straight Line: Baseline is a straight line from lower to upper bound; integration result might be negative.
- Linear Fit: Baseline is a straight line fitted (from below) to the signal; integration result is positive.
Data Tables without Excel
Users without Excel can now benefit from PEAXACT's concept of Data Tables for data management. In addition to the Excel (.xls) format, PEAXACT now supports Data Tables files in the comma sperarated values (.csv) format. CSV-files are plain text files which can be edited with any common text editor.
Timestamp support for OPUS 3D files
OPUS Reaction Monitoring files and other 3D files typically store timestamps for each individual sample. Using the PEAXACT Data Inspector, these timestamps can automatically be read out and added to the Data Table. Afterwards, timestamps can be used for coloring and arranging samples in the Data Plotter and other grapical reports.
New Validation Report Generator
Testing the predictive capability of calibration models from time to time - and especially when changing the operating conditions of your measurement process - is essential to be sure that the calibration is still valid. The newly designed Validation Report makes model validation much easier. You can validate qualitatively or quantitatively depending on whether you provide test samples with reference values
The report now displays reference values of your test samples (blue) along with reference values of calibration (green) for a better visual evaluation. The evaluation can be done individually for each predictive feature and for each location (in case of location-dependent calibration). Quantitative measures like the prediction error RMSEP and prediction bias are shown.
Online-MCR and Online-HMFA
The PEAXACT Application Server now provides two calibration-free analyses: Multivariate Curve Resolution (MCR) and Hard Modeling Factor Analysis (HMFA). If you use PEAXACT as back-end analyzer within your own application, you will be able to use both methods for either offline or online analysis of measurements.
Perform Analyses in Parallel
The PEAXACT Application Server now provides session domains for performing multiple analyses in parallel. Each session is an isolated environment where analyses execute. E.g., the custom interface for HoloPro uses this new feature, allowing you to apply separate analysis models for multi-probe measurements.
