The bug in the Manhattan plot in PanelCheck 1.4.1 that we reported yesterday is fixed now and we have made PanelCheck 1.4.2 available for download. Get PanelCheck 1.4.2 at the Downloads section.


April 11, 2015:
We have discovered that the Manhattan plot didn't function in version PanelCheck 1.4.1. We therefore removed PanelCheck 1.4.1 and temporarily redirect download traffic to PanelCheck 1.4.0 until this bug is fixed. We are sorry for the inconvenience. Get PanelCheck 1.4.0 at the Downloads section.


March 08, 2015:
We have released a new version of PanelCheck, which contains a couple of small bug-fixes. This version is named PanelCheck 1.4.1. It is available at the Downloads section.

Bug-fix 1: in the p-plot (see tab named "F & p plots") the colouring of lines for p-value did not correspond correctly with the colours shown in the legend (also in the same plot).

Bug-fix 2: in the numerical results of ANOVA in the tab named "Overall" a few lines have been removed (those named "F prod", "F ass*prod interaction" and "F prod / F ass*prod interaction"). All numbers shown are correct (we have checked them really many times since ANOVA was implemented), only colouring of one line was wrong. We removed those lines, since they really were redundant.

Use of PanelCheck to compare panel performance from inter collaborative test

A.N Nilsen, O. Tomic, T. Næs
Matforsk, Norwegian Food Research Institute

Abstract
Simple graphical techniques can be utilised to investigate the performance of individual assessors and to detect individual differences among assessors in a sensory panel. By visualising different type of information in a set of various plots the panel leader can extract relevant information without the need of extensive knowledge in statistics. The joint information content gained from the plots can then be used as a basis for selective training in order to improve performance of single assessors and the panel as a whole.

Six sensory panels, both industrial sensory panels that usually perform quality control and trained laboratory panel, took part in an inter collaborative test evaluating six fruit jelly samples using sensory descriptive analysis. Six attributes were used to describe the samples with repeated measurements. The composition of the fruit jelly samples was based on an experimental design with varying levels of sugar, acid and stabiliser.

Various plots can be generated with PanelCheck to visualise panel performance. To compare results from the inter collaborative test the following plots were utilised: Tucker-1 common scores and correlation loadings plots, correlation plots and line-plots.




November 24, 2006:
We have recieved feedback from a few users that they had problems starting up PanelCheck V1.1.0 due to the following missing dll-file: MSVCP71.dll. This error is most likely to occur when installing PanelCheck on a PC that did not have PanelCheck installed previously.

If you have this problem: how can you fix it?
1. Please uninstall the current PanelCheck version (which should be V.1.1.0)
2. Download and install this one: PanelCheck V.1.1.1.




November 21, 2006:
Release of PanelCheck v. 1.1.0.
We are pleased to announce the release of PanelCheck v. 1.1.0 with a great deal of new features. This should further improve usability and increase your efficiency when exploring the data of your sensory panel.

Get more information about the new features here.

Get the latest release for free from the download pages.




September 29, 2006:
The first PanelCheck courses are to be held from february 20 -22, 2007.




September 28, 2006:
Margrethe Hersleth has stepped down as the leader of the PanelCheck project. Oliver Tomic will take over the responsibilities as the new project leader. The webpages have been updated with new information.




August 9, 2006:
The unicode error that appeared on danish Windows XP systems is now finally solved with PanelCheck v. 1.0.3. See news message from May 30, 2006.




July 30, 2006:
Release of PanelCheck v. 1.0.3.

This release contains two important bug-fixes:
1. In previous versions PanelCheck might return a false F value for attributes where that assessor has zero variation for that attribute. This affected F plot only. MSE plot and p*MSE plot were not affected of this. This is fixed in PanelCheck v. 1.0.3.

2. When disabling one or more attributes in the attribute checkbox-list, the 'Raw Data'-button in the plot returned wrong data. This did NOT affect the calculation of any of the plots. This is fixed in PanelCheck v. 1.0.3.

Other than that there were some smaller enhancements in the user-interface of the PanelCheck. The Tree-Controls (left side of the panel) that produce plots by double-clicking them have got different colours, such that attributes and assessor can be distinguished easily. See all changes.




July 12, 2006:
More detailed information about the courses for the use of PanelCheck are now available.




June 18, 2006:
Release of PanelCheck v. 1.0.2. This release handles problems that some users experienced when reading data from Excel files. Added a progress bar that indicates how much time loading of sensory data will take. Read the changes from the previous version.




May 30, 2006:
Unfortunately a few users experience problems during or after installation of the PanelCheck. The error message often contains something that looks similar to this:

"UnicodeEncodeError: 'ascii' codec can't encode character u'\xe6' in position 15: ordinal not in range(128)"

We are working hard to fix this problem and hopefully we will come up with an solution soon.

This is an ongoing project, and as such we would like to invite users to inform us of any bugs that they may find, or any additional features they would like to be introduced. To contact us, then please send an email to: panelcheck@matforsk.no




May 25, 2006:
