Yes, it is intended when I attached it, so it can be changed. When i run the script, I put the filepath, but I still get the x = [0], y = [0] result. Can I see what's the result when you run the script? Thank you for the help.

Hi,
there is a little problem in your python script; have a look to the line where you include the xml file for the models.

you can do it in this way but in your parameter file you have to write :
model['MODEL_LIBRARY'] = 'my_own_models.xml'
or you can put it wherever you want but in this case : model['MODEL_LIBRARY'] = 'path_to_the_xml_file' JulienOn 06/02/2017 09:21, Robertson Esperanza wrote:When creating a new model file, is it necessary that the new model file be saved on the same folder of the default models.xml file?On Mon, Feb 6, 2017 at 3:55 PM, Michele Dolfi <dolfim@phys.ethz.ch> wrote:MEASURE_AVERAGE is compute the average among all sites, i.e. a scalar value.---- Comp-phys-alps-users Mailing List for the ALPS Project http://alps.comp-phys.org/ List info: https://lists.phys.ethz.ch//liMEASURE_LOCAL returns a list of measurements on all sites.Best,Michele--ETH ZurichDr. Michele DolfiInstitute for Theoretical PhysicsHIT G 32.4Wolfgang-Pauli-Str. 278093 ZurichSwitzerland+41 44 633 78 56 phone+41 44 633 11 15 faxOn 6 Feb 2017, at 08:50, Robertson Esperanza <robbie.esperanza@gmail.com> wrote:Oh, I forgot to mention that I'm using mps_optim application.

Since the n_i^2 operator is not yet defined in the model library, you need to add it yourself. Basically I would do as follow:1. Copy the file models.xml from ALPS_ROOT/lib/xml/models.xml, where ALPS_ROOT is the root location of your alps installation.2. Add this definition to your local copy, it defines the n^2 operator<SITEOPERATOR name=“n_squared"site="x"> n(x)*n(x) </SITEOPERATOR> 3. In your input parameters you have now to link to your new model file.MODEL_LIBRARY=“path/to/models.xml” 4. And add your measurementMEASURE_LOCAL[Density^2] = “ n_squared"Hope this helps.Best,Michele--ETH ZurichDr. Michele DolfiInstitute for Theoretical PhysicsHIT G 32.4Wolfgang-Pauli-Str. 278093 ZurichSwitzerland+41 44 633 78 56 phone+41 44 633 11 15 faxOn 6 Feb 2017, at 07:26, Robertson Esperanza <robbie.esperanza@gmail.com> wrote:---- Comp-phys-alps-users Mailing List for the ALPS Project http://alps.comp-phys.org/ List info: https://lists.phys.ethz.ch//liHello, I only started studying many-body physics, so there might be gaps in my knowledge. When using the MEASURE_CORRELATION, why does the measurement goes for only site i<j, is it because there will be "blowing up"? Alternatively, to measure for i=j, i think I could use MEASURE_AVERAGE, of let's say (n_i)^2 where n - n_up + n_down. How could I define such measurement, where you use an operator successively?
