`mp_term` assigned for "Not significant" `classification_tag`

[marinak-ebi]

mp_term assigned for "Not significant" classification_tag which leads to incorrect display on the website.

1. Page with a bug:
   https://www.mousephenotype.org/data/supporting-data?mgiGeneAccessionId=MGI:2150037&mpTermId=MP:0004647

Two significant p-values are shown. However, when we scroll down, the classification is "Not significant," and there is no p-value displayed. The Statistical Method tab also shows N/A values.

2. Solr query for the data from the page:
   https://www.ebi.ac.uk/mi/impc/solr/statistical-result/select?q=colony_id:EPD0002_2_B07%20AND%20parameter_name:%22Number%20of%20lumbar%20vertebrae%22

• Both datasets have the same p-value on the website as in the Solr core.
• The classification_tag is "Not significant" in the Solr core as we see on the website.
• The mp_term was assigned by the annotation pipeline, which means that these p-values were considered significant. Otherwise, the mp_term wouldn't have been assigned.

3. classification_tag is generated by OpenStats R package.

mainAgeing function runs VectorOutput0 function that use classificationTag function from OpenStats:

impc_stats_pipeline/Late adults stats pipeline/DRrequiredAgeing/DRrequiredAgeingPackage/R/sideFunctions.R

Line 2186 in 2ab335e

p1$`Classification tag` = OpenStats:::classificationTag(c.ww0$NormalObj)

Website use classification_tag field from statpacket to generate pages. Issue appears in the statistical pipeline.

4. Search for classification_tag:"Not significant" AND significant:true.
   Five data points for legacy EuroPhenome were found:
   https://www.ebi.ac.uk/mi/impc/solr/statistical-result/select?fl=classification_tag,significant,resource_name,parameter_stable_id&q=classification_tag:%22Not%20significant%22%20AND%20significant:true

To debug this as a first step we need to investigate classificationTag function from OpenStats.
