Cartwheel and FamilyRelations were designed and written by Titus Brown, so, he's pretty much responsible for the flaws in the design and all of the bugs.
Developers: Tristan De Buysscher contributed the current version of the SeqComp program, and is the oldest user of the FamilyRelations software. Madeleine Price is the first person to brave the perils of the FamilyRelations internals; she has submitted several bug fixes and feature enhancements. Ramon Cendejas implemented most of the SUGAR/single view and is responsible for fixing up the pair- and triple-views. Meredith Howard contributed critical comments on Cartwheel/SUGAR, and also wrote the basic geneid and genscan formats parsing code.
Users and Other Opinionated People: Andy Cameron worked with me to find the wrinkles in FamilyRelations and provided informed commentary on what was lacking. In addition, Andy is continuing to provide advice on the future direction of Cartwheel projects.
Erich Schwarz, once he finally started using the software, spurred me on with his enthusiasm!
Advisors: My advisor Eric Davidson had the initial idea of creating the FamilyRelations software, and, together with me, laid out the requirements for the analysis algorithm used in SeqComp and worked through the early bugs in FamilyRelations. Barbara Wold, Tristan's advisor, was the first adopter of FamilyRelations, and consulted extensively with me on its features; she also suggested the triple view feature and motif search feature. Andy Cameron and Erich Schwarz provided me with a sounding board, listened to my complaints about Eric and Barbara's demands for features, and were generally amazingly patient. These four people, more than anyone other than the actual developers ;), are responsible for the creation of this project.
Support: "Titus Brown (that's me) is a participant in the Initiative in Computational Molecular Biology, which is funded by an award from the Burroughs Wellcome Fund Interfaces program." In addition, portions of this (the GeD work, in particular) were funded by a grant from the NIH National Center for Research Resources (NCRR).
