OK - in which case it's clear from the set of options that one of the "custom" options needs to be used  :-)

Hi Steve,

Are you sure?  The issue is that if you collect an Interleaved acquisition with an even number of slices on a Siemen's scanner, then the slice acquired first in time is slice 2 (counting from 1),  which is not consistent with the "Interleaved" option in Feat.

cheers,

Subject: Re: [FSL] interleaved slice-timing correction: odd vs. even slice number

Hi - no it should work fine for any number of slices.

Cheers.

Hi,

I realize FSL generally recommends using temporal derivatives instead of slice-timing correction, but I was wondering if the the slice-timing correction only works correctly for an odd number of slices? I saw this post from a few years back, but it looks like the option is the same:

JISCMail - fsl Archive - Slice timing correction with Siemens scanner (https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=fsl;6dc7322c.0703)

If I have an even number of slices (and Siemens data), do I need to make a slice order file that looks like this (let's imagine 6 slices):
2
4
6
1
3
5

Thanks,
David
