Data explorer v1.4 (Nov 2021-Jan 2022)

  • 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"

      • Added in the "Mutivariate" section

    • 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

API getdata v1.4 (Nov 2021)

  • 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
