| :aligned = batchalign(data,ref_column,target,options) | | Many of our software products come with a "maintenance agreement". The details of this service are given on the [http://www.eigenvector.com/maintagreement.htm Maintenance Agreement Page.] |

|
| ===Description===
| | If your maintenance expires, the software does '''''not''''' stop working. Expired maintenance means you no longer have free access to new releases nor access to our help desk support. |
|
| |
|
| Stretch or contract data columns based on a '''target''' using given '''method'''. Savgol options can be used to exaggerate transitions in data prior to cow.

|
| ====Inputs====
| | ''Related Question: Can I continue to use my license after the maintenance expires? Answer: Yes'' |
|
| |
|
| * '''data''' = (nsample, nvar) dataset or double array containing data columns to align.
| |
|
| |
|
| * '''ref_column''' = scalar indicating the column # of data that we are going to match OR ref_vector which is a vector to use in match.
| | '''Still having problems? Please contact our helpdesk at [mailto:helpdesk@eigenvector.com helpdesk@eigenvector.com]''' |
|
| |
|
| * '''target''' = (nsample, 1) vector or dataset to which we are trying to match the ref_column or ref_vector.
| | [[Category:FAQ]] |
| | |
| ====Outputs====
| |
| | |
| * '''aligned''': dataset or double array (depending on input data type) containing the aligned data. If it is a dataset of different number of rows from input then the class, axisscale and labels are set according to the closest row in input dataset.
| |
| | |
| ===Options===
| |
| ''options'' = a structure array with the following fields:
| |
| | |
| * '''method''': [ 'linear' | {'cow'} | 'padwithnan' ] Alignment method.
| |
| ** 'linear' means the data columns are extented/contracted using linear interpolation to have the same number of data points as the target vector.
| |
| ** 'cow' applies Correlation Optimized Warping to match the reference column to the target vector, then apply the same transformation to the other columns.
| |
| ** 'padwithnan' uses NaN values to extend columns, or truncates columns, to have the same number of data points as the target vector.
| |
| | |
| * '''savgolwidth''': Number of points in savgol filter.
| |
| * '''savgolorder''': Order of savgol polynomial.
| |
| * '''savgolderiv''': [0,1,2...] Order of derivative to take of target and ref_column before doing alignment (default = 0).
| |
| [[cow|Cow]] only options.
| |
| * '''cow.segments ''': number of segments.
| |
| * '''cow.slack''': max range of warping.
| |
| * '''cow.plots''': Governs plotting with COW (0 = no plots).
| |
| * '''cow.correlationpower''': correlation power.
| |
| * '''cow.forceequalsegs''': Force equal segment lengths in "xt" and "xP".
| |
| * '''cow.fixmaxcorrection''': Fix maximum correction.
