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.

Subject: [nighres/nighres] finding QSM (Issue #196)
Hi, we try to make some volumetry with nighres. the database looks like that

the nighres command requests T1, T2* and QSM - which I believe are here, but I can't find them. could you help us?
Thx

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) |
