Capturing and Uploading Only Purple Data from AEwin to a Server

2 views (last 30 days)
Hello! I'm using AEwin software, and when I visualize my data, it's displayed in different colors. I only need the data in purple. Is there a way to filter out just the purple data and capture it? I also want to upload this data to a server in the form of a table.
Can someone guide me on how I can set it up so that as soon as the data comes in, it automatically uploads to the server and gets stored in a table? Is there a way to write a Matlab script for this or any other approach that I could use?
Thanks in advance!

Hi @Umar,
Thank you for the detailed response. The solution you've provided is helpful for filtering and uploading static data. However, my use case involves real-time data capture from AEwin, which doesn't directly log data into files but instead displays it on the interface. The challenge is to capture this data dynamically as it’s visualized and then filter out the purple data points before uploading them to the server in a table format.
Since AEwin doesn’t provide direct file outputs, I am looking for a way to capture the data from the interface itself and then filter the required color data (purple in this case) automatically. Is there a way to integrate real-time screen capture with data filtering and server upload into the process using MATLAB?
Looking forward to any suggestions or further ideas on how to handle this.
Thanks again for your support!

Hi @Huzaifa ,
Your task involves filtering data visualized in AEwin software to extract only the purple data points. Additionally, there is a requirement to automatically upload this filtered data to a server in the form of a table. This document outlines a MATLAB script that accomplishes these tasks.
% Define the server URL and credentials
serverURL = 'http://yourserver.com/upload';
username = 'yourUsername';
password = 'yourPassword';
% Load the data from AEwin (assuming data is in a variable called 'data')
% For demonstration, let's create a sample dataset
data = rand(100, 3); % 100 rows of random data with 3 columns
colors = rand(100, 1); % Random colors represented as values
% Filter the data for purple color (assuming purple is represented by a specific
value)
purpleThreshold = 0.5; % Define a threshold for purple
purpleData = data(colors > purpleThreshold, :); % Filter data
% Convert the filtered data to a table
purpleDataTable = array2table(purpleData, 'VariableNames', {'Column1',
'Column2', 'Column3'});
% Upload the data to the server
options = weboptions('Username', username, 'Password', password);
response = webwrite(serverURL, purpleDataTable, options);
% Display the response from the server
disp(response);
For more information on weboptions and webwrite functions, please click links below.
So, in the above code snippet, script begins by defining the server URL and the necessary credentials for authentication. This is crucial for ensuring secure data transfer. For demonstration purposes, a sample dataset is created using random values. In a real scenario, you would replace this with the actual data loaded from AEwin. The script filters the dataset to extract only the data points that correspond to the color purple. This is done by applying a threshold to the colors array, which represents the color values. In this example, any data point with a color value greater than 0.5 is considered purple. The filtered data is then converted into a MATLAB table format. This is beneficial for structured data representation and is compatible with many data processing and storage systems. Finally, the script uploads the filtered data table to the specified server using the webwrite function. The weboptions function is used to include the authentication credentials. The response from the server is displayed in the MATLAB command window, allowing you to verify the success of the upload.
Hope this helps.
Please let me know if you have any further questions.

Thank you so much for the detailed steps! I really appreciate the guidance on integrating real-time screen capture.
I haven't tried it yet, as I need to set up the system for capturing real-time data from AEwin. Since AEwin doesn't log the data directly, I'll need to run some tests to ensure the screen capture and purple data filtering work as expected. Once I get the real-time setup ready, I will try implementing the method you've provided.
In case I run into any issues during the process, I might reach out for further assistance. For now, this solution looks quite promising, and I'm excited to try it out!
Thanks again for your support.

Hi @Huzaifa,
Thank you for your thoughtful response. I am pleased to hear that the steps provided were helpful and that you find the solution promising. I understand the challenges associated with setting up the system for capturing real-time data from AEwin, especially given its limitations in logging data directly. It’s great to know that you are planning to run tests to ensure everything works as expected before implementation. Should you encounter any issues or have further questions during your setup process, please do not hesitate to reach out. I am here to assist you and ensure a smooth integration. Wishing you success with your testing, and I look forward to hearing about your progress!
