= GIMI Init Script in Exper Mgmt Envir (EME) =


== 1) Goals ==
The GIMI init script in EME aims to interactively initialize the experiment environment for each user-running experiment.

== 2) Tasks for Init Script ==
   * Get experiment name from user, and derive experiment-id
   * Retrieve project_id from omni or CH
   * Get list of slice_ids from omni or CH, select slice_id for this experiment
   * Get sliver_manifests_rspecs from AMs
   * Parse sliver_manifest_rspec to get slice_node_names (fully qualified)
   * Select default GIMI Portal, or override
   * Setup GSAS (iRODS) structure
      * derive defaults for user_irods_home_directory and
      * target(exper)-directory, or override
      * derive and load proj_exper_step_descriptors
      * load template OMF scripts
      * get user_irods_target(exper)_iticket, assigned to selcted GIMI Portal agent
   * Push sliver_manifest_rspecs and exp_descriptors to iRODS 
   * Holding user_credentials, config GIMI Portal exper info:
      * user_identity (from [2])
      * experiment_id, 
      * project_id, and slice_id 
      * slice_node_names
      * sliver_manifest_rspecs
      * user_irods_home_directory
      * user_irods_target(exper)_directory
      * user_irods_target(exper)_iticket
