Check if psftp.exe is in the Sarproz folder.
If not, google it, download it and place it there.
If psftp.exe is there and you still cannot download, write to support at sarproz dot com
we need to check in more detail ur case -
periz started the topic Sarproz Release 2016.00 in the forum Sarproz Forum 8 years, 7 months ago
Dear all,
a new Sarproz release is now available for download through the “manage version” module.
The main improvement is a new module in the “Post-Analysis” frame, “Site Processing” window: the “Time Series Module”.
It’s a new set of post-processing options to export, visualize and analyze the time series results.
Now you can plot and extract…[Read more] -
periz replied to the topic Linear trend threshold in the forum Sarproz Forum 8 years, 7 months ago
why are you surprised that the result is within the imposed range?
the range is used exactly for the purpose to limit the result within a minimum and a maximum.
the result can be different in case of noisy data (the algorithm has a random component, and random data can lead to random results)anyway, never use a-symmetric ranges in the APS…[Read more]

periz replied to the topic Error in co-registration step in the forum Sarproz Forum 8 years, 7 months ago
Hi Amir,
this means that you are missing the matlab parallel processing toolbox.
You should contact your IT person for that. I can anyway send you the compiled version and you can keep both versions on your computer (the license is the same). You can use the compiled one for running the operations requiring functions not installed in your matlab…[Read more] -

hi Shimin,
you should reduce the jpg image and paste it here again, so that we can see the error. Also, if you got a lasterror.mat include it together with the log (zip them before attaching them here).
In the meanwhile, to get an update write to support at sarproz dot com, specifying whether you are using the pcodes version, compiled for win or…[Read more] -
periz replied to the topic Using GAMMA .rslc in the forum Sarproz Forum 8 years, 8 months ago
The coregistration refinement may be needed if you are working with high resolution, high normal baselines, important topography.
We had clear evidence of that with Cosmo datasets in mountainous areas.
Your errors look a bit strange and in fact may be due to the 2015b version of matlab

periz replied to the topic Using GAMMA .rslc in the forum Sarproz Forum 8 years, 8 months ago
Hi Jackie,
unfortunately at this moment the coregistration refinement works only with images coregistered by Sarproz. The reason is that the algorithm is using the results of the first coregistration.
Would that be possible for you to access SLC images? it would also be a chance to compare the result with yours.
We could also implement a…[Read more] -
periz replied to the topic amplitude values in the forum Sarproz Forum 8 years, 8 months ago
Hi Ivana,
you raised a good point. We used to store the normalization constants many years ago, but we did not implement it when we included the SLC module. The image amplitude is normalized to have an average value equal to 1. You could further equalize the images using only stable targets. But the matter of fact is that at this moment the…[Read more]

Tannia,
also, please be aware that memory stays for RAM which is a different concept from disk space.

periz replied to the topic Message from sarproz, during "Sparse Points Multi-image Processing" in the forum Sarproz Forum 8 years, 8 months ago
Hi Tannia,
this is a temporary licensing problem. We have noticed that this may happen if the computer is particularly overloaded and as a consequence almost stuck.
However, it’s not affecting the processing.
Also, notice that the log file you sent is empty and the lasterror.mat file has a different date. In other words, no errors occurred.

periz replied to the topic APS processing parameters in the forum Sarproz Forum 8 years, 8 months ago
Hi Jackie,
it’s a bit a complex matter, there are many things to discuss.
first of all, in the APS it makes no sense to give asymmetric ranges in the parameters estimation. You are processing connections and you have no idea whether you are going to process A-B or B-A.
secondly, again because you are processing connections, you may want to…[Read more] -

periz replied to the topic velocity standard deviations in the forum Sarproz Forum 8 years, 9 months ago
Ivana,
+/- 3*sigma is an operation that has nothing to do with this quantity.
As previously stated, this quantity is not calibrated and it should be simply considered as a measure of the curvature (how wide) is the peak. But again, the value is not much meaningful by itself alone, it’s useful when compared with that of an other target.
Nobody ever…[Read more] -
periz replied to the topic using RCS PSC threshold in the forum Sarproz Forum 8 years, 10 months ago
The basic ideas of Sarproz were firstly conceived during my phd thesis in the years 2003-2005 (check my thesis on Amazon or the urban target recognition paper). At that time I was using ERS and I calibrated the dataset with some corner reflectors. Since then, the calibration constant has been left in the code, and it is used when you process…[Read more]

periz replied to the topic what's the method of SARPROZ choose master image?? in the forum Sarproz Forum 8 years, 10 months ago
The master is chosen in the barycenter of the distribution of normal/temporal baselines.
If you are mixing multiple polarizations, the sw will take a master among images at the highest resolution.
Registration is carried out by cross-correlating patches of images.
Then a polynomial model is fitted in the estimated shifts considering their…[Read more] -
