Are these outputs spaced evenly in time made with the dtDatadump parameter? If not, the problem might be that the LightRay does not know how to detect them. You might try adding the keyword, find_outputs=True, to your creation of the LightRay object. That will search the simulation directory for all available datasets instead of trying to calculate them on its own. This might not work if you have used parameters other than the following to name your outputs:</div>
<div>DataDumpDir<br></div><div>DataDumpName</div><div>RedshiftDumpDir<br></div><div>RedshiftDumpName<br></div><div><br></div><div>Another thing you can do is use the functionality designed to tell you exactly what datasets you need to have in order to span the redshift interval you want. Have a look at that here:</div>
