What do you mean that this is wrong? How can you say it’s wrong?
Don’t be afraid that a temporal noise in this case is not corresponding to a spatial noise.
In space you are applying several smoothing operations (interferogram filtering, unwrapping, APS estimation)
so, it is reasonable to expect a spatial correlation in the results
the problem is…[Read more]

There are no better or worse things. They are simply different and they apply to different analysis/objectives.
Using the Amplitude (Models!) is useful e.g. in the case of temporary targets. You don’t use it in multi-master approaches.

The MST is by definition connected. However, even if theoretically interesting, the MST is practically not very…[Read more]

I looks like the following:
– you are processing a multi-master images graph (it would be nice to see it)
– you are using the coherence as a weight in the inversion (is this the right choice? you need to look carefully at all your interferograms)
That message says that there are points for which some low spatial coherence values break the images…[Read more]

Hi Ana,
data are ok and everything works.
Did you try to save the geocoding window?
In such case, I believe you have overwritten and messed up the pcodes.
You can download the last pcodes version and it should clean up the installation.
Otherwise delete all files (but keep the license!!) and re-install the pcodes from the original tar file.

do the following things:
a. save the small area (“save” button in “small area processing” window). give it a name you like.
b. go to “dataset selection” and click on “export site param”
c. send me by email or wetransfer or whatever you want the .mat file of the small area and the ExportPar.tgz file

select a PS point first

Send the errors please.
By the way, are you using the pcodes version? What’s your Matlab version?

Hi Ana,
we are going to add a check in the code. Anyway, please notice that you are trying to display the quantity “PS Type”, which for sure you did not calculate in your analysis. So, for the moment, simply choose an other quantity to display…

Yes, you found the answer. I was wondering whether you were saving your results after processing.
Please notice 2 things:
a. in your descriptions you’ve never given all the needed details to understand you case. Even more, you descriptions were wrong (you were speaking about the APS module)
b. if you would keep reading the messages from the…[Read more]

first comment:
Sarproz was designed in a way that you never need to repeat steps. even if your computer suddenly crashes in most cases sarproz can recover the job avoiding to start over again.
second comment:
the APS module is aimed at estimating the APS (Atmospheric Phase Screen), not at estimating/saving results as velocity and DEM.
For that,…[Read more]

As I said, it’s a network problem.
Did you resart Matlab?
Check hostname and IP address. There is a conflict somewhere. The workers try to send signals to the main Matlab instance, but it’s addressed in a wrong way and so the parallel job freezes.

Hi Matus,

thanks for the case, we are now including the management of INVALID samples.
In your particular case it may turn out that the adjacent track will better cover the AOI (it’s close to the border).

About the adaptive mask, KS is Kolmogorov Smirnov and DS is Anderson Darling (it should be AD). The connectivity is not used right now, we’ll…[Read more]

if Matlab says it’s busy, that’s not enough to understand if it is calculating things or if it’s waiting for something.
You have to use the task manager in windows to see if there are 4 Matlab parallel processes at full work. Otherwise top in Linux.

how many PSC/Connections are you processing? Also, what is the size of your dataset (samples and lines)? is your data on a local or external disk?

the parallel processing waitbar requires a network protocol to exchange infos between workers
probably this communication was lost in your system and the waitbar got stuck, blocking the processing.
you can check it if the waitbar does not move and there is no matlab instance keeping the CPU busy.
In such a case it should be enough to restart…[Read more]

in the advanced parameters you can change the size of the maximum portion of data to process. lowering that number will limit the amount of processed data.
however, in your case you have more than enough memory. I suppose you have an outdated version with a bug.
do you have the manage version module to download a new one?

you mean you cannot download the precise orbits?
if this is the problem and if you have to do it manually, check the last posts in this topic, to see where to place the files manually downloaded

if the precise orbits are totally missing, then you can use the…[Read more]
