Dear Darren,
<div class=""><br class="">
</div>
<div class="">That’s certainly a creative way to use the inverse warp for the creation of the subject specific grids :). I don’t know what might be going on, but recently we noticed that the warp might go wrong if the metric units of the data object are unexpected.
I am not sure whether this is the case for you, but I noticed that the individual headmodels are explicitly converted into cm. Now, the warping parameters extracted from spm might be agnostic with respect to the units of the input, and probably are defined
in ‘mm’. I know that we have been looking into this (i.e. the unit related issue) recently, but don’t know whether it has been resolved. Just as a diagnostic, could you keep the individual headmodel in mm and check what happens?</div>

<span style="font-size: 10pt;" class="">Wanted to follow-up on a discussion regarding poor normalization, and specifically, an inward bias, when warping template (MNI space) source positions to individual subject space. This is a useful approach to normalization,
facilitating group-level analyses and anatomical referencing, though meaningful inference is predicated on having accurate normalization/warps. At least one relevant discussion thread, here: <span class="Apple-converted-space"> </span><a href="https://mailman.science.ru.nl/pipermail/fieldtrip/2015-April/009111.html" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">https://mailman.science.ru.nl/pipermail/fieldtrip/2015-April/009111.html</a>,

<span style="font-size: 10pt;" class="">In my lab, we’re consistently observing an ‘inward bias’ when warping template source positions to individual space (see attached). Superficial sources seem to shift excessively deep, particularly at the dorsum. Has
anyone adjusted the normalization parameters or implemented alternate warping procedures to generate accurate transformations? I will note that default normalization of individual MRI to template works well in both SPM8 and SPM12 (confirmed with checkreg).<o:p class=""></o:p></span></div>
