18/5/10 v3.0.30
esd calculation updated so that if the mean calculates to 2 or less (rounded so actual value could be up to 2.5 and esd is <=2 then esd is set to 2 as specified in LAB30 section 6.1 of appendix 1. This should have effect of lowering the PV value where esd might otherwise have been lower.

20/3/13 v3.0.32
Alteration to the highlighting for the RICE Trend Analysis in line with the target bands so that a count in Band A will not be highlighted, Band B will highlight in yellow and Band C in red. Ultimately it may be beneficial to display the actual band in a separate column but I will look at this with the next round of general updates.
Limit lines removed from graph .


2/5/15 v3.0.34
Audit updated to correct problem with slides with incomplete initial data set being set to useable. On audit, all slides will be set to unuseable if initial data set is not complete.
AVImport updated to correct problems with slides with an insufficient counts (or no counts) for initial data set. These should now import correctly with entries in the slidesets table and the slide itself set to unuseable.

13/09/16 v3.0.35
Show Month Col option added to System Options screen. If ticked, an additional Months column is displayed in the Counter Performance table (positioned after the Date Counted column). This just displays the month the slide was counted and is derived from the Date Counted entry.

27/6/17 v3.0.36
'Use Latest LRV' option added to system options screen. This option has been added to allow for the differing interpretations of par 6.3 of the UKAS guidelines. The option is ticked by default (meaning that the latest calculated set of reference values is always used in slide PV calculations) but the option can be unticked so that the Set 1 reference values continue to be used even after subsequent data sets are completed. Under this new option, reference values are recalculated every 10 counts (by default) and the new values compared to the set 1 values. If the variation in ESD is greater than 10% a message box is displayed giving the user the option to withdraw the slide from use. If withdrawn, a comment is added to the data set to record the ESD variation.
A slide withdrawn in this way can be re-instated by selecting the slide in the Reference Slides dialogue (it will be highlighted in red to indicate that it has been withdrawn from use). Right-click on the entry, select the Reset Useability option on the menu. The system password must then be entered to reset the slide useability. Note that if the currently active reference values are set as unsuitable then the slide cannot be re-instated.
Note also that if the 'Use Latest LRV' option is changed after data has been added to the database, it will be necessary to run the Audit Database function to recalculate data in line with the new options, as this will affect the calculation of the PV values for many of the slide counts.
A green arrow in the left hand column of the Slide Sets table on the Reference Slides screen indicates the currently active reference values, i.e. those currently used for calculating the PV value of counts performed on the selected slide. For systems where the 'Use Latest LRV' option has been de-selected this will always be the 'Initial' or, when completed, the 'Set 1' slide set. If the option has been left as selected (the default) the arrow will point to the last completed slide set.

Users of previous versions who update to v3.0.36 DO NOT need to make any changes to the system options settings if they wish their system to continue working the same as before. 

Setting the 'Counts in initial data set' to a higher value than the 'Recalculate every n counts' in the System Options sometimes caused the Set 1 slide set values to be calculated using data from the Initial slide set. This has now been fixed. Note also that if the database is audited, the Initial slide data is calculated on the number of counts used when the slide was added to the system, this is fixed and may differ from the 'Counts in initial data set' value in the System Options if this is subsequently changed. This will also be the case if the initial slide set was closed before the default number of entries were added.

'List By ID' tickbox added to Reference Slides screen. Ticking the box re-orders the Slides list sorted by Slide Id rather than the Slide No col.

Entering Slides using the Test Slides function failed to record the number of counts in the Initial Data Set. This caused an error message to be displayed when transferring to the active Reference Slides list and trying to display the Inital Set data. This has now been fixed.

Slide Ref checking added to ensure it is unique when adding to Ref Slides.

Option added to edit existing slide ID if this needs changing for any reason - On the Reference Slides screen select the entry in the Slides table to be edited. Right-click on the Slide ID. Select the Edit Slide ID option from the menu. Enter the system password at the prompt. The Slide ID entry in the table is then editable.

Option added to reset useability for slides which had been flagged as unusable because the suitability was outside the acceptable range. If the slide has been made useable again, on the Reference Slides screen select the entry in the Slides table. Right-click on the Slide ID. Select the Reset Useability option from the menu. Enter the system password at the prompt. The Slide useability is reset.

18/12/19 v3.0.37
'4 Month %' column added to Counter Performance Table to display percentage of counts in previous 4 months which have a performance value within +/-1.25. If the value is below 80% it is highlighted in yellow.
The new value is also displayed on the calculation screen when a new count is added to the table.

To mitigate the problem of yellow chart lines being unclear when viewed or printed out, an option has been added to the fqc.ini file which will enable charts to be produced with thicker lines. 
Add the line:
ChartDrawWidth=2
to display thicker lines on-screen. This also affects output for copying the chart to the clipboard or saving to an image file.
To draw thicker lines when sending to print, add the line:
ChartPrintWidth=10
The values can be adjusted for the best output. The fibre qc application will need to be restarted for any changes in this values to take effect.

23/1/20 v3.0.38 - Update to show 4 month % value to 1dp and problem in Counter Performance grid display corrected.

12/3/20 v3.0.39 - Update to calculte 4 month % by month rather than actual date.

5/11/20 v3.0.40
'Overflow' error fixed which occurred when calculating 4 Month % values on high numbers of counts.

8/11/21 v3.0.41
Plot Recount option added to the Recounts tab of the System Options, to allow the graph to plot the recount value for the mean of 6 when the Counter Rolling Mean is set to Include All Counts. (Previously the graph plotted the original count except the the orignal count was excluded fron the rolling mean.

19/01/22 v3.0.42
In the Re-analysis of Routine Samples module, the Upper Confidence Limit is now set to 3.8 for entries where the original count has zero fibres. Previously, the calculated value came out as zero.
