External Email - Use Caution Dear everyone,
I know that this might be not exactly the right place to ask, but I unfortunately did not reach the authors of the publication so far. I want to work with the evolutionary expansion map by Wei et al. published in Nat Comm (2019; https://secure-web.cisco.com/1EOa2cp_XKYtekyLUN3mqm-iZxVh0pAiE-j1_IvELbdew0_5yco5Qn1zkww73evmjFLHXrpMKk3MTc0UftYqqspUWCnEUttTGobh73r0sLrK4hMDTTJSizcKflNtBNqfTyl0NS51B60IwvBsPsrcslfbsVdLCIjbj4BoGoMOpAmQScRod3QGhL3f8cSiycVoBDa3rvVwLbjfJ4-XsD4jOBXwr5JNfjsjXO9oXVAKmzBdtIH4-G_bH4EZEGPXdEjrocq-7nL1xCjZ0-ENwymFoNFI9Z_3QhFJNvcTLZAXatUskI51ibStKq1lUkZqv4qtfc_w46tNETXWjym-pxRMS7evGrmrL6sH1rEYEwycrDo8/https%3A%2F%2Fdoi.org%2F10.1038%2Fs41467-019-12764-8). On their website, they provide a download link leading to two mgh files (attached; https://secure-web.cisco.com/1wjBHK0nX5LW0U-Wy1w4rY2bystAnHOCIGlVB_T3xRlPwIA1GVvz1pnhCXNC-ia3gnO6FjNtV1pHo2kBNR-Trh5WGlM_e_m6scOf3l8S_0o7rH0SA6Zrn1r6TiqnYqPrACKxhJuGwJ5VzTWlt3WfIQwA0cUywAN5JdXGTmA2PoXdu46XvoRQkV8_nCrPu7KGUhpYo6wJ0o66GZlKJGZoGL9GznJ1khVE-gs2j9XBIl2DEvrfc1c4XcHa_nI5VeWJhgH1jhVc1FwdSQl2JpT7sndUQQRIxPnxXpLYPBbj0ZlL5KifRziPz7JhkCH4iA0cs2PrBGr9xDqQgkZIADtx4QIM6r59o8EkYYRxTCM_UMbI/https%3A%2F%2Fwww.dutchconnectomelab.nl%2Fwordpress%2Fwp-content%2Fuploads%2FWei_et_al_2019_NatureComms.zip). I read them with the Matlab load_mgh.m function provided here (https://secure-web.cisco.com/1-0OpH0qgfeFpbCMfaVWHm-btTsT6A2ZX44WYfXtCEzjf9bUgQx9CtSi1F45Kk1C855ajx5fNyPBZ7ryU16uJTKx-bTTGtGAzgfOzPkgNgbJfxUH5fhP9wskCP-0amwa1EF4H62ViFuPVhpPAyFBRvKMzinmUWXK17KdFpMtzDVp8k3clvsI0Blg78at2fmOmscYyYGwNShEGrqdV0y3pF9waKvMLx6VNYUBPeauFhhBtHW8Y87V5yOPW9n2DoPUjshSly0_6vqjiVTEx2pgU1MFVv9l3DcdZlxcy7Mbut75yrfmZ8mSFEpJDNS3H3Mq9luH-QoQYLFxVkSQMyi1WKlVCtTJsqqYlD4tf52SeGX8/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FFsTutorial%2FMghFormat) and it shows a 163842 x 1 vector (which probably corresponds to fsaverage6 I guess...). I now want to convertthe 1D vector back into 3D. I have come across save_mgh.m but don't know what should be put in as M (4x4 vox2ras transform). Any ideas what is the correct way to do that? Thank you! Best, Melissa
