Description

VCE is a program to estimate covariance matrices in a rather general manner.

Two methods are available:

  • REML (REstricted Maximum Likelihood) using analytical gradients,
  • Gibbs sampling.

Availability

VCE is available in the 6.0.2 version.

Use

Batch use:

  • prepare the job description script -- use a general skeleton supplemented by the following lines:
...
# load the VCE module
module add vce-6.0
 
# run the computation
vce-6.0.2 my_pfile
...
  • pass the job description file to the scheduler together with the request for a single processor and the requested amount of memory:
$ qsub -l nodes=1:ppn=1 -l mem=XXXg mydescriptionfile.sh

Interactive use:

  • ask the scheduler for an interactive job having a single node and a single processor reserved:
$ qsub -I -l nodes=1:ppn=1 -l mem=XXXg
Note: Do not forget to apppropriately set the amount of requested memory (mem attribute) and/or another job requirements.
  • load the VCE module into the environment:
$ module add vce-6.0
$ vce-6.0.2
