The usual stand-in is a net rendered as a maf, which loses the level structure that makes a net useful for establishing orthologous sequence. bigNet holds the netAlign columns in a bigBed, so a hub can carry the net itself. The format is bed6+20: the target in chrom/chromStart/chromEnd, the query sequence in name, the query strand in strand, then level and the rest of the netAlign fields. The trackDb line is type bigNet mirroring type netAlign. chainTrack is the plain trackDb name of the bigChain track in the same hub; hgc adds the hub prefix itself. chainNetLoadRangeHub() builds a chainNet from a bigBed range query and hands it to the same helpToNet() the SQL path uses, so the nesting is rebuilt the same way. netDraw picks its loader off tg->isBigBed and the drawing code below that is untouched. genericNetClick does the same for the details page and follows the named chain track for the alignment. Also bounds the level walk in helpToNet() by help->maxDepth. It could read one past the end of the levels array. netToBigNet converts a net file to bedToBigBed input. It writes the tab line itself rather than calling bigNetTabOut, because autoSql prints a double with %g and that drops digits off a chain score. diff --git src/hg/htdocs/goldenPath/help/trackDb/trackDbSettings.yaml src/hg/htdocs/goldenPath/help/trackDb/trackDbSettings.yaml index 8e7f1b36c9a..ed148214e8d 100644 --- src/hg/htdocs/goldenPath/help/trackDb/trackDbSettings.yaml +++ src/hg/htdocs/goldenPath/help/trackDb/trackDbSettings.yaml @@ -25,32 +25,32 @@ - name: type_for_hubs types: - all roles: - super - composite - view - leaf category: Common Settings context: trackDb level: required required: true summary: Declares the format of the data and is used to determine display methods and options. description: 'Declares the format of the data and is used to determine display methods and options.
