Panacea xQTL review Wed 9 nov 2011

  • Data curation and annotation of the Panacea Database (joint effort)
  • Host project analyses:
    • Phase 1: Just add the R scripts as files for basic provenance
    • Phase 2: Being able to rerun important scripts such as sample mislabeling and QTL x Env
    • Phase 3: Make it easy to add and run any R script that was used
  • Data matrix:
    • Download or visualize with CytoScape
    • Need new view with more organization/hierarchy: group by experiment or annotation
    • Need to couple this hierarchy with the ability to quickly run scripts for visualization or statistics on a piece of the data
  • Need 'supersearch' which produces reports on concepts (ie. everything related to a marker or individual)
    • This should include a special 'QTL finder' tool to quickly create reports on findings using a matrix and/or traits as inputs
  • Focus on pathways:
    • Want to query pathway information for an organism from 1..N sources (GO, WormBase, KEGG.. ?)
    • Want to couple existing gene annotations to these pathways, semi-automatically (?)
    • Want to use this information to run analysis/visualizations on these batches of genes
    • Want to create pathway plots (biology!) with the gathered information (e.g. QTL profiles)
    • Want to create CytoScape graphs of e.g. correlation of the genes

EURATRANS xQTL review Wed 9 nov 2011

  • Integrate with genome browser (gBrowse, formats WGL and GFF)
  • Need to save any filter as a URL
  • Need to clarify how a tool like gBrowse can specify a 'range' in filter URL syntax and link it
  • Also need the 'range' to work on matrices with locus data (e.g. markers) via URL
  • Need to add scripts as visualizers of data: e.g. let them appear in a list of possible plot types in matrix
  • Search box bugs: no '_name' searches possible
  • Use real column names instead of labels eventually, this is still very confusing
  • Need for advanced matrix views:
    • On similar rows & columns, create 'subheaders' with multivalue display
    • Alternatively, matrix merge operation to concatenate them
    • Want to have a report on a value that appears in multiple matrices
    • And/or reports with plots for e.g. a marker or probe with all related information from all sources

xQTL LL user workshop Fri 28 Oct 2011 general comments

  • Need more download formats: STATA, SAS, CSV (not TSV)
  • SNP data should somehow include metadata such as: imputed (yes/no), genome build, reliability, dosage, etc.
  • There should be a way to merge (part of a / a filtered) phenotype set with a genotype set, and retrieve the result
  • The application can be slow, need more speed
  • There are too many tabs, GUI is unclear
  • Need an hourglass (or something) to indicate the application is busy (blackout screen with progress bar when busy, GeneNetwork style?)
  • Making selections is too complex
  • Column paging is confusing
  • Filtering works 'half' (Joris please explain)
  • Data viewer should be able to create selections using your own file
  • Id's should be unrecognizable
  • Search filter should work on all measurements by default
  • Filters are lost when a user pages, this is annoying
  • Like other waiting times, applying a filter should cause the app to refresh with a 'wait please' status
  • Merging pheno- and geno sets is a special case of using a shopping cart (batches) to save selections for re-use elsewhere, this should be implemented. So you make a selection of participants based on phenotypic criteria, and then you view SNPs of interest for only those selected, and vice versa.
