AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

I have modified mri_read_dicom.c to fix this problem in the following ways:
1) If you set environment variable AFNI_SLICE_SPACING_IS_GAP to NO, then this fixup will always be disabled
2) The fixup (dz = sp+th instead of dz=max(sp,th)) will be made if AFNI_SLICE_SPACING_IS_GAP isn't set, only when sp < 0.99*th, instead of the condition sp < th as before. This should prevent your weird case (where sp is just a tiny amount less than th) from happening automatically.
3) If AFNI_SLICE_SPACING_IS_GAP is set to YES, then the dz=sp+th fixup is always applied. This would only be required if you have these faulty (GE) DICOM files and are using very large gaps.

Source code is available now, and linux binaries are compiling as I type this.
