Dear PhysIO Experts,

This is the second time I am using PhysIO Toolbox on my research. At the first time, I used physio.log files, from a Philips Achieva 3T of the Univ. of Birmingham. I opened the file on Matlab and easily defined thresholds for slice, volumes and etc.

Now I am using distinct log files, also from a Philips Achieva 3T, but from Univ. of Campinas. There are lots of prep. pulses and also 5 dummies, I create the Matlabbatch similarly, but I notice that there is no consistent peak at the beginning of each volume, so, it is impossible to define the thresh.vol, since sometimes, the slice amplitude is higher them some "volumes start" peaks. I am aligning from the last scan, I identified the inter volumes time, defined the number of slices and volumes + dummies, but the toolbox is still considering prep pulses (only them in fact). Looks like it still searching from the "first" or tottaly missing all the real data.

Any idea? Physiolog file attached.

TR = 2 secs
40 slices
400 volumes
5 dummies

Thank you very much!
