pipe table
Field | data type | description |
|---|---|---|
pipe_id | index |

modified | timestamp |

name | varchar |

pipetype | VARCHAR(256) | fMRI,phys,T1,VBM |
description | varchar | user-entered description |
linkpipe_ids | varchar (string vector of numbers) | pipe_ids of pipe dependencies (input data) |
archive | boolean | flags unused pipe; because we do not want to duplicate pipe_id’s, best to hide rather than delete unwanted pipes |
