I use top, only one matlab process is running, as describe below:

That was strange, it has occupied only 5% of CPU

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?

Here is the Matlab windows

Thanks for you attention, the Matlab parallel pool is still busy, but waitbar is still 0%.

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]

Yeah, you are quite right, I reset the parameters as your recommendation, in which:

1. DL=0;
2. Linear trend

I am using a dataset mainly located in the urban area, I re-run the “Sparse Point Selection” and “Graph Creation”, but stopped at “Connection Processing”, the runtime window shows as below

In fact, I do this step in last evening, and…[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 I suppose you have an outdated version with a bug.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]

you need a good amount of patience and experience to become able to play correctly with the parameters and to be able to judge what is wrong in the results.
I do not know the details of your dataset and of the area you are processing, so, I cannot give precise suggestions.
Also, which images graph did you use?
Anyway,
a. why are you setting DL=30.…[Read more]

Could be, I am playing SARproz on a 4 core, 16GB machine. I am curiosity why the memory leak happen in the middle? Is there a memory control option in SARproz, like the Doris?

it looks like a memory problem, something that we never saw at this step. how much RAM does your system have?

Dear Prof.Daniele

I used ERS-2 for processing, I want to co-registration, but for “set Orbits” option, the precise orbits unavailable. Any suggestion what must I do?

Best Regards,

Thanks for your advice, I shall reinstall the right version of Matlab today. Would you take a glimpse of the error file? I will zip them this time.

Before attaching MAT and LOG files, please zip them first.
If the DEM is not well aligned, using the coregistration refinement will mess up your data.
Since you could not choose a GCP because you are using Matlab 2014b, highly probably your DEM is not well aligned.
Generally speaking, the coregistration refinement is needed only in particular…[Read more]

As you can see here http://www.sarproz.com/pcodes-instructions/
Matlab 2014b and later are not yet supported and the reason is exactly a big change that Mathworks implemented in the graphic management.
