I am trying to load an ascii into Netlogo with apply-raster from the GIS extension.
While I did this many times before (although not with this specific ascii), netlogo now throws the following error:
extension exception: 1944553
error while observer running GIS:APPLY-RASTER
I am not sure why this is happening.
The ascii has a projection file with it (WKT), which should work fine:
GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]
The ascii itself has these parameters:
ncols 1481
nrows 1314
xllcorner -10.577897001
yllcorner 49.902509998994
cellsize 0.00833333333333
NODATA_value -9999
I am running these four lines for loading the ascii and resizing the world.
set my-dataset "data/my-folder/my-file.asc"
resize-world 0 gis:width-of (gis:load-dataset my-dataset) - 1 0 gis:height-of (gis:load-dataset my-dataset) - 1
gis:set-world-envelope-ds (gis:envelope-of (gis:load-dataset my-dataset))
gis:apply-raster (gis:load-dataset my-dataset) my-variable
Is anyone familiar with this error?
Or is there a place where I can look up what this extension exception means? I could not find it, but maybe I am looking in the wrong places.
Thanks!

I'm pretty sure there is an off-by-one error in RasterDataset.resample, but I've never had the time to look into it. You should be able to work around this issue by removing the "- 1"'s from your call to resize-world, i.e.,
resize-world 0 gis:width-of (gis:load-dataset my-dataset) 0 gis:height-of (gis:load-dataset my-dataset)
If that doesn't work, let me know and I'll see if I can find time to investigate further.
The issue was finally solved after recreating all ascii files. Even though there was no apparent difference in the old and new ascii files, the old files must have been corrupted somehow. The code in the question works fine now. Hopefully this topic is still helpful for anybody running into the same error.

I just started using GNU Radio, I must say I am quite a noob but I have some background on RF related stuff.
Here's the thing:
I recorded a file that I now want to repeat through my HackRF and GNU Radio.
This is the exact settings for the filter:
The settings you see are casual (since I cannot get it working I started testing with random values).
This is the error I get:

Done (return code 1)
Where obviously the interesting part is the RuntimeError: firdes check failed: 0 < fa <= sampling_freq / 2
Unfortunately, I don't get what that 'fa' stands for.
Any idea?
Cheers
I just got done solving this same error. The error is caused by a filter's Cut-off and transition parameters being set incorrectly (in my case far too large). GNU radio handles the variable 'samp_rate' differently for each block and filters seem to interpret it was a point to center the filter on (that's my take on it so don't quote me).
I also looked in the source code and can't find anything helpful on 'fa'
So try adjusting your cutoff to be something below samp_rate and make your transition width something to the tune of 250e3. I used GUI sliders to set the filter how I liked and I will make these permanent in the final version.
Screen Cap of Settings Here
Slider Settings For Both Sliders
Mike Ossmann's "SDR with HackRF One, Lesson 10 - Filters helped" me out here. Also just a great SDR lecture series for GNU radio if you haven't come across them yet. (just make sure to use the QT GUI).
I hope this helped. I am pretty new to GNU so sorry if the explanation is a little half-baked.
fa is the cutoff_frequency in the function that is throwing the error message. The cutoff frequency has to be greater than 0 and no more than the Nyquist limit. There are some functions called sanity_check_xxx (xxx being whether one cutoff or 2, i.e. bandpass, and optionally c for complex) around line 750 in gr_filter/lib/firdes.cc in the GNU Radio repository on GitHub.
In the question the samp_rate would need to be at least 800MHz to support a high pass cutoff of 400Mhz. As far as I can tell sample rate is used the same way in these filter functions as anywhere else in GNU Radio.
I ran into the same error message because I used 'firdes.band_passinstead offirdes.complex_band_pass` and the low cutoff was negative, which it should be for the complex band pass filter.
The Systemverilog code below is a single file testbench which reads a binary file into a memory using $fread then prints the memory contents. The binary file is 16 bytes and a view of it is included below (this is what I expect the Systemverilog code to print).
The output printed matches what I expect for the first 6 (0-5) bytes. At that point the expected output is 0x80, however the printed output is a sequence of 3 bytes starting with 0xef which are not in the stimulus file. After those 3 bytes the output matches the stimulus again. It seems as if when bit 7 of the binary byte read is 1, then the error occurs. It almost as if the data is being treated as signed, but it is not, its binary data printed as hex. The memory is defined as type logic which is unsigned.
This is similar to a question/answer in this post:
Read binary file data in Verilog into 2D Array.
However my code does not have the same issue (I use "rb") in the $fopen statement, so that
solution does not apply to this issue.
The Systemverilog spec 1800-2012 states in section 21.3.4.4 Reading binary data that $fread can be used to read a binary file and goes on to say how. I believe this example is compliant to what is stated in that section.
The code is posted on EDA Playground so that users can see it and run it.
https://www.edaplayground.com/x/5wzA
You need a login to run it and download. The login is free. It provides
access to full cloud-based versions of the industry standard tools for HDL simulation.
Also tried running 3 different simulators on EDA Playground. They all produce the same result.
Have tried re-arranging the stim.bin file so that the 0x80 value occurs at the beginning of the file rather than in the middle. In that case the error also occurs at the beginning of the testbench printing output.
Maybe the Systemverilog code is fine and the problem is the binary file? I have provided a screenshot of what emacs hexl mode shows for it's contents. Also viewed it another viewer and it looked the same. You can download it when running on EDA Playground to examine it in another editor. The binary file was generated by GNU Octave.
Would prefer to have a solution which uses Systemverilog $fread rather than something else in order to debug the original rather than work around it (learning). This will be developed into a Systemverilog testbench which applies stimulus read from a binary file generated in Octave/Matlab to a Systemverilog DUT. Binary fileIO is prefered because of the file access speed.
Why does the Systemverilog testbench print 0xef rather than 0x80 for mem[6]?

Update:
An experiment was run in order to test that the binary file may be getting modified during the process of uploading to EDA playground. There is no Systemverilog code involved in these steps, it's just a file upload/download.
Steps:
(Used https://hexed.it/ to create and view the binary file)
Create/save binary file with the hex pattern 80 00 80 00 80 00 80 00
Create new playground
Upload new created binary file to the new playground
Check the 'download files after run' box on the playground
Save playground
Run playground
Save/unzip the results from the playground run
View the binary file, in my case it has been modified during the process of
upload/download. A screenshot of the result is shown below:
This experiment was conducted on two different Windows workstations.
Based on these results and the comments I am going to close this issue, with the disposition that this is not a Systemverilog issue, but is related to upload/dowload of binary files to EDA playground. Thanks to those who commented.
The unexpected output produced by the testbench is due to modifications that occur to the binary stimulus file during/after upload to EDA playground. The Systemverilog testbench performs as intended to print the contents of the binary file.
This conclusion is based on community comments and experimental results which are provided at the end of the updated question. A detailed procedure is given so that others can repeat the experiment.
I am still new in Octave with some experience in Python and I was requested to do a test in a stimulus application in order to find if there are errors in the code (not developed by me) and try to fix them and run the application. The issue in the code is at the time to open the screen as follows the implementation (these ones where I commented (%) are what already did before, and these ones below the comments are my correction) the code is large with 825 lines:
%% Get subject name from the user
prompt = {'Enter Subject Number:','Enter Subject Name:','Enter Todays Date:','Left or Right:'};
dlgtitle = 'Information Input';
%dims = [1 50];
dims = [1 50;1 50;1 50;1 50];
opts = 'on';
answer = inputdlg(prompt,dlgtitle,dims);
%waitfor(answer);
waitfor(dims);
%% TO Excel
% Get the name of the file that the user wants to save.
%startingFolder = userpath;
startingFolder = 'C:\Users\Vtr\Downloads\Final-task-981203\Final-task-981203\Task-981203';
defaultFileName = fullfile(startingFolder, '*.xlsx');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a filename ');
if baseFileName == 0
% User clicked the Cancel button.
return;
end
% Combine the folder and base file name into the full file name.
fullFileName = fullfile(folder, baseFileName);
%% LOAD text initial setting
%% Create 1st screen : (Loading and Wait)text screen
% Open an on screen window - purple screen
[window, windowRect] = PsychImaging('OpenWindow', screenNumber, [0.5 0.5 1]);
% Set up alpha-blending for smooth (anti-aliased) lines
Screen('BlendFunction', window, 'GL_SRC_ALPHA', 'GL_ONE_MINUS_SRC_ALPHA');
After that, in the first part is created a form to insert subject nº, subject name, today's date and left or right, and after that to specify a filename. Made these two parts it appears a purple screen with the mouse's cursor rotating non-stop and if I try to click with the mouse an error alert box "octave-gui.exe has stopped working" appears on. I already tried to run this code on my Virtualbox-VM (Ubuntu 16.04 LTS), firstly, it notifies that my screen is being tested and calibrated and after, it appears another error screen on the terminal:

Im having an error while trying to compile an .air from Flash CS5.5. The error says:
Usage error (incorrect arguments)
Filename contains restricted low-ascii character 13:
Im using a version of the file which compiles correctly on XP, now Im trying to compile on OsX but it doesn't. Any clue?.
Thanks in advance
Different operating systems use different characters to mark the end of line:
Unix / Linux / OS X uses LF (line feed, '\n', 0x0A)
Macs prior to OS X use CR (carriage return, '\r', 0x0D)
Windows / DOS uses CR+LF (carriage return followed by line feed, '\r\n', 0x0D0A)
In your case, ascii 13 = carriage return.
It is probable that one of your air project configuration files has an embedded carriage return that is causing this error.
You should try a utility such as linebreaks
Less likely but not impossible, is that one of your actual file names contains a carriage return.
For that you will need to try and rename the files till you find the correct one.
The problem is that the compiler says that there is a redefinition of a function between a library that belongs to MySQL and math.h from the std library.
I have been over this for two days and I still can't figure it out.
Has this ever happened to anyone?

Thanks in advance!!!
This thread in the mysql support area seems to indicate that they've taken the definition of rint() out of their config_win.h file as of April this year (even though the patch was proposed in 2006). Are you using a version of the MySQL source newer than that?
The problem was about an included library, which linux simply ignores, but windows want out. There is no problem letting it out in linux neither...
Somedays i feel SOOOOOOOOOOOOOOOOOOOOOOO STUPID:..
In line 228 of c:/Archivos de programa/MySQL/MySQL Server 5.0/include/config-win.h you should find a declaration/definition of function named "rint". In line 620 of C:/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../include/math.h you should find another definition of a function with the same name (which probably even does the same).
To solve the problem you will have to delete/outcomment/undefine one of these definitions.
Be prepared to get a similar problem when linking, if you also link two libraries with the same function.
