External Email - Use Caution Dear Freesurfer team,
I am trying to use mri_WMHSynthseg for white matter hyperintensity segmentation. I have installed the latest dev version, and I understand I need to download an atlas file from " https://ftp.nmr.mgh.harvard.edu/pub/dist/lcnpublic/dist/Histo_Atlas_Iglesias...https://secure-web.cisco.com/1rKqiV3c2UqdiIsJcAkgN6Rp80ECVnAQhuP-ybfrZvES9uRBuXZByvRIhn-iB0NmHTmoeoUEuCQNXQzjJS4HSHnsKxvv_jzziUS4cgpOD3cWbfBk2ftDIWc_Vb2BiTNxkLEtpwVLjVkGpkFG5nZCLVQDClQX9fePFWvwXkXo1ThsK8VttWrm_C_lAX0RfThnyWBGzqbTys5dGQ1Mknc-6afLMwyZq2JfcIjIqjjdELC4iotntJzH-lu6H6u-H_y_hsncGBQtdrxw1ewfeFJeSRf5QZ3bm_ubATPVhOwI7OuueiBeRizZ75DBnnPDo7w0KutVcL5hgwgJmPnvsu1o0hxjG8mCHDYU2cL3uE0Zb4lA/https%3A%2F%2Fftp.nmr.mgh.harvard.edu%2Fpub%2Fdist%2Flcnpublic%2Fdist%2FHisto_Atlas_Iglesias_2023%2Fatlas.zip". However, I get a 404 error when I try to access this url. Upon examining the server, I see that https://ftp.nmr.mgh.harvard.edu/pub/dist/lcnpublic/https://secure-web.cisco.com/1mPu-NE2sUuQ7fyqENpvjVu3_TN_mht4HgGfcxc1kLZmIQgueDDA-g_DJ1Fp6C3BKlzSx01W9DEOtmfpYqzLzxbmYDHrTsM7WaPynOJjoc5GKa14fH5NkwLi2egEVEK2SHoSaAok_u-yHuSIhuUOqQt8NcVaOADXFZk7bUkWA71Mxc-rbKom5c2oNcddLnWYpxZ42hoaKMFdzPR-amauT1fZJi_rpFLoUpilWqQK72-wNALVakFbbyZhH7TeOqDvOJY7eLnyYFSEywV7C2o3xl0Ji2V7adGcwqzKfJXLWWzUsoXGsjNqp5qJigrYeVUu7OBotJb9F8eS_T_wiOycZbrJcYY4h73wLUGRG884z8lE/https%3A%2F%2Fftp.nmr.mgh.harvard.edu%2Fpub%2Fdist%2Flcnpublic%2F is empty.
