Updates to README Additional Information (from review 2022-01-12)

[GregConan]

• Copy-paste some of the description from the more thorough infant pipeline documentation?

Outputs subsection

• Update the output directory tree
  • E.g. executive_summary is now in a different place, named differently, has different contents, etc.
  • Include T2 outputs in the tree

Rerunning subsection

• Either move the one sentence to somewhere more relevant or add an example of its usefulness

Special Pipelines subsection

• Clarify that this means special options, not a special different pipelines
• Remove the point about the abcd-task module and replace with a reference/link to Greg's and Anthony's abcd-bids-tfmri-pipeline

Misc subsection

• Mention that the pipeline does not(?) currently run with gradient field maps
• Add link to BIDS Spec for PEPolar field maps
• Clarify whether PEPolar field maps are the only BIDS-valid kind recognized by the pipeline?

Some Current Limitations subsection

"We're gonna punt on everything that was described in these first 3 paragraphs" -Thomas

• Replace part about diffusion field maps and DWI processing with a link to QSIPrep
• Change "automatic reading of physio data from BIDS format has not been implemented" to "will never be implemented"?
  • Add a link to movement regressors power plots and DCANBoldProc so readers know where to get that functionality?
• Delete the word "currently" from "Software does not currently support" in last paragraph, and also remove the last sentence (which is confusing and may not even be true)
