webread error 122 - after it has already worked

10 views (last 30 days)
here is the relevent part of my code:
for i= (1:length(ralstonia_uncharacterized_idx));
if matrix_ralstonia(i)==1;
formatspec = 'https://www.UniProtKB.org/uniprot/%s.xml';
A1 = raw_ralstonia.ID{i};
url= sprintf(formatspec, A1);
o = weboptions('CertificateFilename','');
xml = webread(url,o);
%finding the general vicinity of name
expression = '<fullName evidence.*</fullName>';
gene_name_raw = regexp(xml, expression, 'match');
% focusing on the name
focused = '>.*<';
gene_name = regexp(gene_name_raw, focused, 'match');
raw_ralstonia.gene{i} = char(string(gene_name));
end
end
it has worked for many times, and now after a week I attended some other things I tried this again and it gives me the error massage:
Error using webread (line 122)
I didn't change a thing, and worked through the same terminal. I tried in other url's in another site, and the same error massage prompts.
WTH?
thanks in advance...

Hi Chaim
It seems like the domain name in the URL is not in use any longer. You can change the URL to https://uniprot.org/uniprot/A0A0J9DKQ4.xml and use the webread function.
Hope this helps !

so now to the problem with blastncbi:
this one (just copied from a code that worked) doesn't work for me:

%Blast the inputted sequence against NCBI protein. Return 5000 results.
[blastsend, waittime]=blastncbi(POI, 'blastp', 'MaxNumberSequences', 5000);
and the error massage is:

not established because "error setting certificate verify locations:
CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: none". Check your system certificates for expired, missing, or invalid certificates.
Error in blastncbi (line 184)
s = webread([site commandPut blastUrlString]);
so I see it uses webread, and I gather the problem is that here I can't add the part which exempts me from certification
o = weboptions('CertificateFilename','');
xml = webread(url,o);
how could this be tackled?
thanks.
