[MINC-users] NaN handling in RMINC

[RW]

Hello,

I’m using minc toolkit 1.9.17 on the mincvm-packer ([Update for Virtualbox 6.1.12 and packer 1.6.0](https://github.com/CoBrALab/MINC-VM/commit/15ca2dd0ee9287136232da4fe8e3ac9104c3437a)) via Windows Oracle VirtualBox 6.1, with lubuntu 18.04, and R version 3.6.3 and RMINC version 1.5.2.3.

When performing simple linear regressions using mincLm on RMINC, I notice that if one of the scans contains NaN values (via minccalc), the resulting Betas (regression coefficients) appear to have implausible ranges (e.g., “Range: 3230528607327814463144632678524911616.000000 -0.061514).

Is there a way I can ensure that NaNs of a given subject are ignored in the Beta calculations?

Thank you for your assistance,

RW
