FBIRN HID/SRB upload scriptsFBIRN HID/SRB upload scripts

• Protocol in the HID– Subject groups– Scans and assessments that are part of the protocol are defined

• Assessment and demographic data for the subject in the HID

• Images on the SRB– XML metadata files with Images on SRB

• The upload script consists of over 35,000 lines of code – distributed over 768 files which includes binaries for converting images, – adding/editing/changing XML, inserting and querying the database,

instructions/manuals.....Etc.

XCEDE: EventsXCEDE: Events

• We have defined an XML structure to store events, which are time intervals [onset, onset + dur) that are associated with arbitrary user-defined metadata. Types of events might include stimuli, responses, blocks, QA metrics, etc.

FIPS: Analysis LevelsFIPS: Analysis Levels

• Preprocessing – MC, STC, B0, Smoothing, Brain Extraction, Registration • First Level – Estimate amplitude of HDR, Significance• Higher Levels

• Visit, Subject, Group, Cross-Group, …• Fixed, Random, Mixed Effects

• Stimulus Schedule – EPrime• FIPS Database and Web page • QA – All Levels (nothing in FIPS yet)• Mostly FSL-based
