Editing GSCAN (section)

== Authorship guidelines ==

While authorship is decided on an individual basis for each GSCAN paper, typically, authorship is arranged in groups. We hope the GIANT investigators will forgive us for adopting and adapting their authorship guidelines. 

'''Author Ordering'''

* A group of usually 6 or fewer junior investigators who strongly led the efforts, usually starred to denote equal contribution, followed by additional junior investigators who played key, central roles.
* In alphabetical order, junior investigators who had substantial individual contributions but not as much as those in Group 1. Typically, these might be lead analysts or other junior investigators who made a sizable contribution such as GWA analyses performed specifically for the paper.
* In alphabetical order, all investigators who do not belong to another group. In some cases, there may be an additional group of junior investigators who had notable individual contributions but not as much as those in Groups 1 or 2. 
* In alphabetical order, senior investigators who participated strongly in GSCAN activities but did not strongly lead/oversee the writing and/or analysis for the paper. Typically, these might be leaders of key GSCAN activities.
* The senior investigators who strongly led/oversaw the writing and/or analysis of the paper, including a subset that are co-corresponding authors (usually 6 or fewer).

'''Proposal for number of authors'''

Given the author categories above, we expect each study to propose a reasonable number of authors, in line with the number of authors from other studies. In our experience, there are typically 3-5 "study-specific" authors. Study-specific authors include local analysts who generated summary stats as well as PIs or others who supervised the local study work. These authors are in addition to any individuals associated with those studies who contributed in significant ways to the central meta-analysis or writing.  Particularly large or complex cohorts may have higher limits; if you believe your cohort fits this description, please discuss with [[mailto:vrieze@umn.edu Scott Vrieze]] or [[mailto:dajiang.liu@gmail.com Dajiang Liu]]. Of course, in all cases, authors must meet the broadly accepted criteria for authorship.
