Hi, I am newbie here. But right now I am doing a research my study. I can’t run stamps(1, 1) eventhough I load stamps and train in matlab. Any helps or suggestion is so much appreciated because I am running out of time.
Here is the log:
>> help stamps
stamps Stanford Method for Persistent Scatterers
stamps(START_STEP,END_STEP,PATCHES_FLAG,EST_GAMMA_FLAG) Default is to run all steps.
A subset of steps may be selected with START_STEP and/or END_STEP
STEP 1 = Initial load of data
STEP 2 = Estimate gamma
STEP 3 = Select PS pixels
STEP 4 = Weed out adjacent pixels
STEP 5 = Correct wrapped phase for spatially-uncorrelated look angle error and merge patches
STEP 6 = Unwrap phase
STEP 7 = Calculate spatially correlated look angle (DEM) error
STEP 8 = Filter spatially correlated noise
STEP 0 = Continue from the last known stage till the end-stage selected
PATCHES_FLAG Default ‘y’. Set to ‘n’ to process all data as one patch
EST_GAMMA_PARM is an optional parameter passed to PS_EST_GAMMA_QUICK
PATCH_LIST_FILE is an optional argument specifying the file list of
patches to be processed. Note that from step 5 and above one should use
all patches to merge results.
If current directory is a single patch, stamps only operates in the
current directory, but if current directory contains many patches,
stamps operates on them all.

>> help aps_linear
[ph_tropo_linear] = aps_linear(save_path)
Scipt to compute the tropospheric delay map from a linear relation
between phase and topography, optional a non-deforming polygon can be
specified by setting crop_flag to ‘y’ in the parms_aps list.
The computed tropospheric delay is in the same units as the
inputed interferogram phases.
All required inputs will be read from the aps_parm list. This includes:
non_defo_flag ‘y’ or ‘n’ to use a non-deformaing region.
Polygon of the non-deforming area. By default ‘n’ the whole
interferogram is used. Change to ‘y’ by using setparm_aps.
Note that this variable is a matrix with in its columns the
longitude and latitude of the non-deforming area.
hgt_matfile Path to the interferograms
Interferogram phases, given as a column vector or matrix
with in its columens the different interferograms.
Stamps structure will automatically be recognised. Use
setparm_aps so change the data path pointing to the .mat
file.
hgt_matfile Path to the heights file.
Colum vector of the topography.
Stamps structure will automatically be recognised. Use
setparm_aps so change the data path pointing to the .mat
file.
ll_matfile Path to the longitude and latitude file
Matrix with in its columns the longitude and latitude.
Stamps structure will automatically be recognised. Use
setparm_aps so change the data path pointing to the .mat
file. In case the poly argument is specified, both need to
have the same units.
OUTPUTS:
ph_tropo_linear The topography correlated delays either estimated from a
linear relationship over the whole interferogram of using
a non-deforming region. By default the output of this
function is stored in the ‘tca2.mat’ or ‘tca_sb2.mat’
for StaMPS SM and SB option. In case no StaMPs
structure is used the data is saved in ‘tca2.mat’.
