Hi Pawel,
we could change that piece of code to allow you using that function with your old matlab version.
However, you may find other issues later on. If it is easy for you to upgrade matlab, please do it. If you cannot, let us know and we will make those changes

If you are using MATLAB R2011a or previous version I would suggest switching to R2012a or later.
I will leave this to Dan for adding comments.

Hi,
I have run into a problem with downloading the weather data. When I try to get it there is an error message as follows: “Undefined function or method ‘narginchk’ for input arguments of type ‘double'”. So I tried to skip this step and do without the weather data. That didn’t work because the coregistration process seems to require temperature…[Read more] -

Hi Periz
How can i download SRTM manually and place them in that folder?Thanks

periz replied to the topic Error on "Dem visualization" in the forum Sarproz Forum 7 years, 3 months ago
Those are not errors
they are informative messages.
If in your area no SRTM files are available, there is nothing wrong. If SRTM should be available, then the software cannot download them for some reasons. Do it manually and place them in that folder -

Hi Wang,
First of all, thank you for taking a carefully look at the log before processing the data to the next step.
Sentinel uses a method called spectral diversity (SD) for coregistration in order to meet the strict restriction of Sentinel TOPS coregistration. To give a simple explanation it uses the spectrum of TOPS for coregistration.

Dear periz,
Thank you very much for the answer, I updated the software and the coregistration work successfully.But I didn’t find the log file for coregistration.
Also as I just complete the coregistration, although the matlab reports that the coregistration was concluded succesfully, I saw that for one image there is warning information. I put…[Read more]

periz replied to the topic pcodes installation in the forum Sarproz Forum 7 years, 3 months ago
hi Thibault,
to use Sarproz in matlab, you need the pcodes, which is a set of more than 1,500 files with extension .p, and which comes in a zipped file, pcodes.tar. If you have the main.exe file, instead, it means you have the compiled version that runs independently from Matlab. You cannot call main.exe from within Matlab.
Please send an email…[Read more] -

Hello,
I have a problem with the installation of a pcodes version with Matlab.
I can follow the steps on the installation sheet but when I write fig=main; on Matlab prompt, I have the following answer :
Undefined function or variable ‘main’.
I am well in the directory C:/pcodes that I have created with the file main.exe extracted from the .tar…[Read more] -

Dear Bridget,
it is always useful to include the full log file in order for us to read more infos and better understand your case.
It seems to me that both issues should belong to an old software version, the last update should have solved them.
In any case, none of them represent a real problem for the success of the processing.
Please check you…[Read more] -

Dear all,
I encountered with these warnings in the coregistration step for sentinel1-A.
Could you please tell me the reason and how to correct it ?
Thank you so much.

periz replied to the topic Using for two different study area in the forum Sarproz Forum 7 years, 4 months ago
is this error happening in both matlab windows or in just one of them?
I am afraid this is a problem of that particular matlab version.
We tested it with versions equal or higher than 2014a and it works -
periz replied to the topic Using for two different study area in the forum Sarproz Forum 7 years, 4 months ago
are you opening two matlab windows and running a sarproz instance in each of them?
-
periz replied to the topic Using for two different study area in the forum Sarproz Forum 7 years, 4 months ago
Launch it twice.
But make sure the two instances are not using the same CPU cores, or as a result they will run slower. You may want to assign half number of CPU cores to each instance. Moreover, one of the bottle necks of InSAR is the quantity of data: if you don’t have very fast disks, attempting to read data from multiple disk locations at the…[Read more] -
periz replied to the topic APS Processing in the forum Sarproz Forum 7 years, 4 months ago
The NL weights are used to decide which coherence values are good and which are not good.
In fact, the value of the coherence is not universal. The value depends on the dataset that you are using (number of images and distribution of baselines) and on the parameters that you estimated (as deformation model, height and so on).
The sw runs a test to…[Read more] -

there is some error relative to the coordinates
before the error you report here an other one happened, it would be useful to look into it
also, we may need to check the contents of the hand_slc_module structure that you can get by typing “fast” at the command prompt -
