Massachusetts General Hospital/Harvard Medical School

Louis Gagnon of MIT and the MGH-Martinos Center for Biomedical Imaging contributed code for using short separation measurements to regress physiological interference while simultaneously estimating stimulus evoked hemodynamic responses (Gagnon2011, Gagnon2012). See hmrDeconvTB_3rd(), hmrDeconvTB_SS3rd(), hmrDeconvTB_SS3rd_Highest().

Rob Cooper while at the Martinos Center contributed to several functions related to correcting motion artifacts. See hmrMotionCorrectSpline().

Katherine Perdue of Dartmouth College contributed code for identifying motion artifacts based on a standard deviation threshold to complement the amplitude threshold. See hmrMotionArtifact().

Juliette Selb of the Martinos Center contributed to several functions related to correcting motion artifacts. See hmrMotionCorrectSpline().

Sabrina Brigadoi, while visiting from University of Padova, contributed to functions related to correcting motion artifacts. She adopted the wavelet method described by (Molavi2012) for Homer2. See hmrMotionCorrect_Wavelet().

Jichi Medical University

Daisuke Tsuzuki and Ippeita (Pepe) Dan (Functional Brain Science Lab) are helping to incorporate their registration tools into Homer2 (Tsuzuki2012). These tools will be part of the AtlasViewerGUI tool.

University Hospital Zurich

Felix Scholkmann and Martin Wolf of the University Hospital of Zurich contributed a motion correction algorithm using splines, as described in (Scholkmann2010). See hmrMotionCorrectionSpline().
