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. -

I crop the area smaller, which up to 5000 * 6000 pixel, but it still frozen there, since I set the DL=0, the top command shows only one eternal occupied process is by MATLAB, though somehow parallel MATLAB workers show sometime.

Dear Ivana,
I’ve taken a look at the log file, and there’s a very stupid error in the last version of sarproz that causes the tops-post-processing (a second-time fine coregistration) not able to finish.
And the wrong result in interferogram is exactly the consequence of the tops-post-processing (fine-coregistration) not able to finish.
We…[Read more]

And at last,
I am attaching what I got as interferograms. Two of the interferograms look reasonably, two of them contain the stripes noted in the last post and the rest (7) of images look like this (attached): stripes in coherence.
(in the last post, I forgot to note that 20150703 is the master image.)
Do not know whether it can be caused by…[Read more]

Hello again,
I keep on processing, despite some images do not cover the whole area. I have encountered two errors I do not understand:
the first is in the lasterror.mat and .log files,
the other is the scshot documenting one of the resampled slaves (I would expect black at the end of the image, but not a stripe…) there are two images like…[Read more]

Thank you Yuxiao,
no, I mean something else:

Hi Ivana,
Sorry for asking this, I want to get a clearer idea about your question: are you referring to the overlapping of different subswath? Can you give a few screenshots or something so I can have a better understanding towards your question?
Thanks!
Yuxiao

Hello again,
the S1 images do not overlap by 100% (although the bursts should be synchronized, they are put to different images each time), but according to ESA, it can be tiled seamlessly (in the azimuth direction). My area has such a problem: in some images, it is contained as a whole, in some images, only part of it is contained.
I also tried…[Read more]

Hello,
also thanks for the TOPS module.
Seems to me (not critical) that the UPDATE mode in the SLC DATA IMPORT module does not work… if I press Slave Extraction, it tells me to use Master Extraction first… and the Master Extraction does not work either.
(encountered more times)
I.

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]

Hi Matus,
Yours is indeed not S1 image but TOPS based on the sarproz log file.
This is something we never encountered and I will be more than happy to take a look.
Just while I was doing the investigation, can you also tries to update to the newest pcodes, clean up all the directories and start with only the SLC folders again? During the last…[Read more]

Hi,
thank you all for a good job and for putting your effort into developing S1 TOPS processing and adaptive mask. I’ve been eagerly following updates last days and I’ve tried to produce coregistrated stack of 8 S1 images. However, in versions from last days (7-Aug, 12-Aug, 14-aug) I get half of extracted Master and Slave images black. I was…[Read more]

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. -

Dear all,
during this summer we worked at two new important updates.
The first one is Sentinel TOPS. Yuxiao developed the code for reading it, stitching bursts together, coregistering and resampling.
A beta version is now included in the pcodes, we’ll soon add it also in the compiled code.
The module works now on single subswaths (one has to…[Read more] -

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?
