  * Data directories
    * **primaryData** - all your source data for your history and calibration usually lives in: /models/<model>/primaryData (note NOT under the version number)
    * **referenceData** - all the various data that will inform your projections & comparisons in the simulation time /models/<model>/referenceData (note NOT under the version number)
    * **viewData** - data informing views including: past user interaction, custom aggregation mappings, parameters for reference scenario: /models/<model>/<Version>/viewData

===== Working with data =====
The articles in this section discuss how to interact with data files external to the model.
  * [[howtos:workwithdata:Overview of reading data]] FIXME
  * [[howtos:workwithdata:Data Format vs File Format]]
==== Preparing files ====
In general the data files should not be touched!  Try hard to take the data file from it's source and manipulate it 
in the model or in a view to fit the objects you need to file.

If, however, you want to prepare an empty file to then get others to fill in:
  * [[howtos:workwithdata:Prepare empty file from documenter]]

==== Reading data ====
  * [[howtos:workwithdata:A Simple Import View]]

  * [[howtos:Reading data into arrays]]
    * [[howtos:Importing Informant Definitions - Sets and Categories]] FIXME /*- shona*/
    * [[howtos:workwithdata:createSetsFromDataFile| Use create to make set informants from data file and use them for a test load]]
    * [[howtos:workwithdata:createReadDataFiles| Use create pick apart complicated data files]] 

  * [[howtos:workwithdata:Importing and tabulating record-based datasets]]
  * [[howtos:workwithdata:Geographic data]]FIXME /*- shona*/
  * [[howtos:workwithdata:Example - Import from Beyond 20/20 (.ivt) format | Reading Beyond 20/20 (.ivt) data]]FIXME /*- Marcus*/

  * [[howtos:workwithdata:Creating Import Templates]]
  * [[howtos:workwithdata:Importing/Exporting time slices using a for loop]]

=== Examples ===

  * [[howtos:workwithdata:Import Quick Reference| Import and create examples]] - example ''import()'' and ''create()'' calls



==== Writing data ====
  * [[howtos:workwithdata:Export Views]] FIXME 
  * [[howtos:workwithdata:Export to .csv]]
  * [[howtos:workwithdata:Export to "template" format]]

=== Examples ===

  * [[howtos:workwithdata:Export Quick Reference| Export examples]]




===== Calibration =====
  * [[howtos:calibration:Projecting Into History]]

===== Feedback/Tracking Methods =====

Root finding methods. See http://en.wikipedia.org/wiki/Root-finding_algorithm

Brute force:
  * [[howtos:feedback:Tracking Method - Deviation ratio multiplier]]
  * [[howtos:feedback:Tracking Method - Deviation ratio addition]]

More specialized/sophisticated:
  * [[howtos:feedback:Tracking Method - Minimizing Root Mean Squared Difference with 5 point bracketing]] - bi-section variant
  * [[howtos:feedback:Tracking Method - Minimizing Root Mean Squared Difference with 5 point bracketing]] - yet to be implemented

  * [[howtos:debugging:Model Debugging in SAMM]]

===== Administration =====
==== Using a hosted model ====
  * [[howtos:admin:Connect to model hosted at whatIf?]] 

==== Administering your own server ====

Setup:
  * [[howtos:admin:Server Systems Requirements]] 
  * [[howtos:admin:Setup server from scratch]]
  * [[howtos:admin:Setup User and Model Accounts|User and Model Accounts Setup]]
  * [[howtos:admin:Model Family Directory Structure]]

Common tasks:
