Thanks Darren.  So, should I also set SPM.xX.K.X0 to 0, or is only
SPM.xX.K.HParam = Inf necessary to turn off the filter?

I looked for it in the SPM5 GUI, but it's not there.

The funny thing about the multiple postings is, I didn't use an e-mail
client, I posted through the website - and I promise I didn't hit "post"
more than once!!

I tried setting it in the batch interface and it appears to work fine.
Inf
is accepted as a value and the resulting SPM.mat file has a field
SPM.xX.K.HParam = Inf. The SPM.xX.K.X0 field has size 175x0 (I have 175
scans in my dataset), but it is empty. It also estimates properly. 

Where were you trying to do this in the GUI?


by the way your email client seems to send multiple messages to the
list.
