It looks like you have all the ingredients: the mp2rage gives you T1 directly, the t2star multiecho can be used to get T2* (flash_t2s_fitting in nighres) and QSM (using your favorite QSM package, I use tgv-qsm but only because the others are in matlab). Check the latest testing example (v1.5) for some qmri recobstruction code, too.

Hi, we try to make some volumetry with nighres. the database looks like that [image]https://user-images.githubusercontent.com/104447628/252719305-899a3ef3-934a-42b1-b90f-26bdb316eea6.png the nighres command requests T1, T2* and QSM - which I believe are here, but I can't find them. could you help us? Thx Shahar

Just to make sure - which of the files I have to use in order to create the QSM?
the t2star_multiecho is likely a flash-type sequence: you can get the T2* from fitting the magnitude, and the QSM from processing the phase (often both magnitude and phase, depending on the method you use)
