Hi Bruce,
Thanks for the reply. The talairach.xfm file generated by the palarellizing machine is empty; it looks as follows:
Talairach.xfm file:
MNI Transform File
% avi2talxfm
Transform_Type = Linear;
Linear_Transform =
However, the talaraich.xfm file generated by the non-paralellizing machine is the following:
MNI Transform File
% avi2talxfm
Transform_Type = Linear;
Linear_Transform =
1.088816 -0.036409 -0.059575 1.880753

Hi, FS Experts,
I?m using version 5.3 and have performed hippo-subfields analysis.
To perform the statistics, shall I get the normalized volumes of each hippo-subfields? or just to do correction for ICV is enough ?
thanks..
Hyon

Postdoctoral Opportunity: Multimodal MRI registration and analysis
Context and methodology This postdoctoral position will focus on the registration of ex-vivo onto in-vivo MR data. Based on some recent advances extending the combined volume and surface registration, efficient approaches can be provided for dealing with this issue. However, these methods need to be validated and several open theoretical questions are related to this problem and will be investigated during this postdoctoral work. The theoretical results obtained will be tested and used on real human data in a larger framework aiming at tractography validation (French National Research Agency Grant ANR 2014, collaborative study Inserm U930, Universit? de Tours, Neurospin and Martinos Center).
Applicant profile Candidates should have a strong background in image registration and MR imaging, a good publication record, and strong experience in c++ and matlab coding. Proficiency in English is required, as well as scientific writing skills. Applicants should send a CV, including list of publications and a description of previous research experience, as well as the names and emails of two academic referees to: Clovis Tauber ( clovis.tauber@univ-tours.fr mailto:clovis.tauber@univ-tours.fr) and Christophe Destrieux (christophe.destrieux@univtours.fr mailto: christophe.destrieux@univtours.fr )
Conditions Starting date: January 2016 (adjustable) Contract: 2 years Location: Imaging and Brain unit, INSERM U930, Tours. Salary: related to experience

wow, we haven't seen that happen. Does the recon-all.log from the parallel machine have any clues as to why it is empy? On Mon, 26 Oct 2015, Anna I. Garcia Diaz wrote:
