-
Collection management
- Adding a collection information section including the list of metadata in addition to the list of datasets
-
Possibility to select several data subsets
- Consideration in graphics (colors, legend)
-
Extension of query-string parameters
- In addition to the type of analysis and the data subset(s), it is possible to specify the factor(s) and the variable(s).
-
Possible change of the theme colors
- parameterization in global.ini
-
Customization of the title "ODAM Dataexplorer"
- by replacing it with a custum label with its corresponding URL
- parameterization in global.ini
-
Addition / extension of biostatistical analyses
-
Mean comparison of factor levels
- Added in the "Univariate" section
- Case where 'Factor for Grouping' is identical to "Factor for X Axis"
- Possibility to select levels when the number of factor levels > 3 (Select First Factor Levels)
-
Volcanoplot (Anova)
- Added in a new section "Multi-univariate"
- Possibility to select the factor levels (Select First Factor Levels)
-
t-SNE: "r t-sne plot"

HeatMap && GGM
- limitation to 150 variables based on the most significant correlations
-
Graphes
- Add partial correlations as a graph
-
-
Intersection between data subsets
- Integration of the UpSetR tool
- Either For all data subsets (UpSetR tool)
- Or according to the selection of data subsets (Venn diagram if 2<nb<4)
-
Management of large data tables in the data explorer
- When loading, keep only the first variables within the maximum allowed (1000 by default).
- Thus just put the most significant and/or interesting variables first in the attributes table.
- Creation of the script to sort the variables in the file a_attributes.tsv according to their significance (see scripts/odam_reorder_vars.R)
-
Numerous improvements / corrections
- Numerical Identifiers & Numerical factors better managed
- Addition of the type of correlation in Multivariate / Correlation
- Addition of polygons encirclement for PCA/ICA/t-SNE
-
Added the possibility to format the datasets information page (infos.md) with a specific CSS file.
-
Upgrade to R 4.0
-
Added sqlite 3.0 to speed up response times on large files as data query system (default q-Text-sql)
- Added the "build" service to build the database from the tabulated files.
-
Adding an authorization mechanism by key, possibly associated with an IP number.
- Parametrization within a file authkeys.tsv to be added in the dataset directory
-
API with XML format - XSLT transformation:
- Merge the two columns "CV_Term_Name" and "CV_Term_ID" into one 'CV_Term' with a link
-
Upgrade to PHP 7.2
