HaploGrep’s RestAPI now available!

Hi all,
due to many requests we are happy to announce┬áthat we provide Haplogrep’s┬áREST API to the public! This will allow everyone to determine haplogroups in a very convenient way. In the following snippets we show how a simple call works (a) from the UNIX command line using curl and (b) from Java. If you have an example running for other languages, please let us know and we will add it here.

Happy haplogrouping & happy new year!
Sebastian

1) Unix Command Line: This call uploads the file myfile.vcf and returns a JSON String including the tags “id” and “haplogroup”:

curl -i -X POST -H "Content-Type: multipart/form-data" -F "importfile=@myfile.vcf" https://haplogrep.uibk.ac.at/haplogrep-ws

2) Here you can see the exactly same call with Java:

import org.restlet.resource.*;
import org.restlet.ext.html.*;
import org.restlet.data.MediaType;
import org.restlet.data.Status;
import org.restlet.representation.*;
import org.json.*;

import java.io.File;
import java.io.IOException;

public class SampleClient {
public static void main(String[] args) throws IOException {
// change location here
File file = new File("/home/seb/samplefile.hsd");
//POST file
ClientResource cr = new ClientResource("https://haplogrep.uibk.ac.at/haplogrep-ws");
final FormDataSet fds = new FormDataSet();
fds.setMultipart(true);
final FormData fileRep = new FormData("importfile", new FileRepresentation(file, MediaType.APPLICATION_ALL));
fds.getEntries().add(fileRep);
cr.post(fds);

//Response
JSONArray jsonArray = new JSONArray(cr.getResponse().getEntityAsText());
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject object = jsonArray.getJSONObject(i);
String id = (String) object.get("id");
String hg = (String) object.get("haplogroup");
Status status = cr.getResponse().getStatus();
}
}
}
