This script calculates estimated current time courses for each trial
---
USAGE:
function vb_job_current_tr(proj_root,parm)
or
function vb_job_current_tr(parm)
--- Input parameters
- parm.resultfile : Current variance file (.bayes.mat)
- parm.currfile : Average current is saved.
Infomation of current file are also saved.
current of each trials are saved into 'jactdir' directory
.curr.mat file
- parm.jactdir : output directory of current files for each trial
relative path from proj_root
do not include '/' or '\' in the end of string
If 'jactdir' is not given, jactdir = 'temp'
---- Optional (default)
- parm.areafile ([]) --> focal window
.area.mat file.
- parm.area_key ([])
ID of interested area.
- parm.tsubsmpl ([]) --> whole time points
Time points where currents are calculated. For example,
if tsubsmpl = [1:5:100], currents are calculated at only every 5 sample
point.
- parm.overlap_mode
= 0 : current is averaged over overlapped time window
= 1 : current is not averaged for overlapped window
current time series of each time windows
are concatenated sequentially for spectral analysis
* Parameters saved in output file (.curr.mat)
- Jact
- Jbck
- ix_act
- ix_bck
- Lact
- Lbck
- Varact
- bayes_parm
- vb_parm
* Example
>> proj_root = '.'
>> parm.areafile = 'NG/data/100009d.area.mat';
>> parm.bayesfile = 'NG/result/result3_col.bayes.mat';
>> parm.trial_average = OFF;
>> parm.area_key = 'fMTl';
>> parm.currfile = 'result/result3_col_fMTl_1.curr.mat';
>> parm.jactdir = 'temp';
>> vb_job_current_tr(proj_root,parm);

Parameter name changed within this code for readability
(just replacing 'resultfile' to bayesfile)
