[Mne_analysis] Coregistration {Disarmed}

Hi Matthew,

This is complicated as the essential information is not shipped in a standard way with the HCP MEG data. To circumvent these issues we created mne-hcp https://secure-web.cisco.com/1s-DF5dLfrUaphxYz8JgDwGSCC3GqbjemJQ2raMsz2LHdzMUXq2fFWpClOXXQFiLJGhZ3elhfSJAGzn47DOk8wcSOy2rBvZvgZIXIg1NrxiB1APHGoE-e_Fys8uW8SUKKcMfkaQ9BxSiSb4hSieqxHJQ9Y0-fSeAbsMt6qLrrBWax1Immq3UtKPQXyzsOoSStY7up8oyb3rfMBF-KqC3AQQ/https%3A%2F%2Fmne.tools%2Fmne-hcp%2F which extracts the important bits and pieces from the HCP data and applies the necessary transforms to use the coregistration that comes with HCP. See for example how to compute a forward model https://secure-web.cisco.com/1_XJSnV4UXVlHiZnEVyqC5vGmZtY_Ldcq3AuK2YfESxFovf3pFq5GKWyaO8n4o9Nsa1Vy_SwocPUnSin8nR74j4IGzWVXPtkHRCE0imkcvsDDT4mSwMZgoMT4FY38R_AjTnYdlWO9UgCWKG4LKFUxY7rSB0mUbScaFB38S9l7I4ZHO69W6FFJ4aHhK8HzmVZoBDRk_wQqUypomufRb8I9PA/https%3A%2F%2Fmne.tools%2Fmne-hcp%2Fauto_tutorials%2Fplot_compute_forward.html%23sphx-glr-auto-tutorials-plot-compute-forward-py or source localization https://secure-web.cisco.com/1Uv5hEoBgaVhO0l5i8sT0aJ0VVevJqwG2hzoMo-pG9LwjaV8CwlmxtiPkIjbdQr4ZAIveqxQA9i6-qQhMhmHrcVOj39MUueQPof1XKMDSxGAu-B0_1mpD9S_AhHWJkoofGRDGRHwe1ynOpQFUcZc70UoeG1MConUvLvFL7gC_HyzuWzRp1yamr-xsa5JSeTNWNvb6eSHSB5870lRmWumpnQ/https%3A%2F%2Fmne.tools%2Fmne-hcp%2Fauto_tutorials%2Fplot_compute_evoked_inverse_solution.html%23sphx-glr-auto-tutorials-plot-compute-evoked-inverse-solution-py

Hope that helps,
Denis

It is typically in an info[‘dig’] for each participant. Can someone help me figure out how to best locate this information or if there are workarounds?
