Hello,
I want to obtain chemical properties from certain subtances from the website chemicalize.com. However, to access my account, I have to put login and password information. How can I automate this process using MATLAB?
For the login information, I used this code, but it keeps giving me the error
"Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 396)
The server returned the status 419 with message "unknown status" in response to the request to URL
https://pass.chemaxon.com/login.
Error in readContentFromWebService (line 46)
byteArray = copyContentToByteArray(connection);
Error in webwrite (line 139)
[varargout{1:nargout}] = readContentFromWebService(connection, options);
Error in smilestocheminfo (line 4)
z = webwrite(url, options);"
Code:
url = 'https://pass.chemaxon.com/login';
options = weboptions('Username','username','Password','mypassword');
z = webwrite(url, options);
Please help!

Do you have write permissions for the directory you are cd'd to?
