Dear Alps users,
I'm running a simulation with loop application and an 1D Chain of Heisenberg spins. I'm interested in the correlation study between two of these spins as a function of the temperature and the interaction parameters.
I need to run the simulation to 300 parameters (temperature + parameters) I really need to write in the parameter file 300 lines? Or is it possible to do it in another way?
After I ran the simulation the param.task*.out.xml files have different sizes:
. Files with 2.3 M:
<SCALAR_AVERAGE name="Energy^2"> <COUNT>1007616</COUNT> <MEAN method="jackknife">445.73115</MEAN> <ERROR converged="yes" method="jackknife">0.00979</ERROR> <VARIANCE method="simple">58.8</VARIANCE> <AUTOCORR method="jackknife">0.321</AUTOCORR> </SCALAR_AVERAGE>
. Files with 20 M

Is it normal to have these diversity of output? Can I choose any option to just have the first kind of files? Is there any way to select that I just want the correlation between two given spins?
The output of "Spin Correlations" is the average of the whole component: Sx_i Sx_j + Sy_i Sy_j + Sz_i Sz_j or just the Sz_i Sz_j ?
Thanks in advance for your kind support
