Galaxy: tabular patterns

This is the runtime-facing map for Galaxy tabular transformation choices. Use it before loading raw survey notes. The survey remains evidence backing; the operation pages are the actionable references.

Row And Column Operations

tabular-filter-by-column-value — keep/drop rows by string column value with Filter1.
tabular-filter-by-regex — keep/drop rows by regex or pattern matching.
tabular-cut-and-reorder-columns — project and reorder columns with Cut1.
tabular-compute-new-column — compute row-wise values into a new column.

Joins And Aggregation

tabular-join-on-key — join two tabular datasets by key columns.
tabular-group-and-aggregate-with-datamash — group and aggregate rows with datamash_ops.
tabular-sql-query — use SQL when filtering, joining, and projection are clearer as one query.

Text-Processing Recipes

tabular-prepend-header — add a header row with an awk/text-processing step.
tabular-synthesize-bed-from-3col — build BED from three-column tabular inputs.
tabular-split-taxonomy-string — split taxonomy-like strings into useful columns.
tabular-relabel-by-row-counter — synthesize row labels from row order.

Bridges

tabular-to-collection-by-row — split a tabular manifest/list into collection elements for map-over.
tabular-concatenate-collection-to-table — row-bind a collection of tabular outputs into one table.
tabular-pivot-collection-to-wide — outer-join a collection of id/value tabulars into one wide table.

iwc-tabular-operations-survey — tabular-operation survey and evidence trail.
galaxy-sequence-patterns — companion MOC for sequence-record operations; FASTA↔tabular is the dominant sequence seam.
galaxy-interval-patterns — companion MOC for coordinate-feature operations.
galaxy-collection-patterns — companion MOC for collection operations.

Sequence: relabel FASTA headers via tabularrelated pattern— Edit FASTA headers you cannot easily regex in place: fasta2tab, rewrite column 1 with find/replace, then tab2fasta back. The high-value sequence recipe.

Sequence: compute record lengthsrelated pattern— Emit a (id, length) table from a FASTA so downstream tabular steps can filter, sort, or threshold records by length; fasta_compute_length.

Sequence: interconvert FASTA and tabularrelated pattern— Move sequence records between FASTA and a (header, sequence) table so tabular tools can edit them; fasta2tab one way, tab2fasta back.
