I am employed as an HPC Scientific Programmer and will be leading (and probably doing it mostly myself ☺) this project. If you want more details regarding our plans, please let me know, since I don’t want to bore you with the details in this first email. I also have a technical question. I’ve added simple applications, along the lines of Add, Echo, Multiply … etc. without a problem. I’ve also added an application that takes an input file as an InputDataObjectType of type DataType.URI. However, I must be doing something wrong when trying to generate output files i.e., OutputDataObjectType of type DataType.URI. RegisterSampleApplicationsUtils.createAppOutput("output_file", "", DataType.URI); It seems to work fine with strings still, since if in my script I put something like this: echo "output_file='file://localhost:///opt/lampp/htdocs/PHP-Reference-Gateway/experimentData/spiros340e527dece195a74ac7455fbcc6f6fa/spiros_c.eps'<file:///\\localhost:\opt\lampp\htdocs\PHP-Reference-Gateway\experimentData\spiros340e527dece195a74ac7455fbcc6f6fa\spiros_c.eps'>" Then it picks up the string. My question is: how do I declare in the script that I want an actual file, not a string? I’ve tried: output_file='file://localhost:///opt/lampp/htdocs/PHP-Reference-Gateway/experimentData/spiros340e527dece195a74ac7455fbcc6f6fa/spiros_c.eps'<file:///\\localhost:\opt\lampp\htdocs\PHP-Reference-Gateway\experimentData\spiros340e527dece195a74ac7455fbcc6f6fa\spiros_c.eps'> output_file=”file://localhost:///opt/lampp/htdocs/PHP-Reference-Gateway/experimentData/spiros340e527dece195a74ac7455fbcc6f6fa/spiros_c.eps<file:///\\localhost\opt\lampp\htdocs\PHP-Reference-Gateway\experimentData\spiros340e527dece195a74ac7455fbcc6f6fa\spiros_c.eps>” and with the keywords “set”, “declare”, and “export” in front of “output_file” but have had no success. I think I’m missing something in the whole concept of output files, but as a first step to better understand output files within Airavata, I would like to know how to hardcode sth. like that in the script and see it appear as a… URI type? For example, as a string it shows up like this: array(1) { [0]=> object(Airavata\Model\Workspace\Experiment\DataObjectType)#15 (4) { ["key"]=> string(11) "output_file" ["value"]=> string(127) "'file://localhost:///opt/lampp/htdocs/PHP-Reference-Gateway/experimentData/spiros340e527dece195a74ac7455fbcc6f6fa/spiros_c.eps'<file:///\\localhost:\opt\lampp\htdocs\PHP-Reference-Gateway\experimentData\spiros340e527dece195a74ac7455fbcc6f6fa\spiros_c.eps'>" ["type"]=> int(0) ["metaData"]=> NULL } } But the array is empty when I try one of the above lines in the script (output_file= …). Thanks in advance, Spiros
