BIAC's Processing Pipeline is a software system designed to automatically transfer data off of the scanner, run a series of automated processes on the dataset, and transfer the processed results to a directory where the user can get to it. This process depends on proper assignation of the dataset to a valid Experiment. Once assigned, data is processed according to Experiment based preferences, and the results are transferred to the appropriate Experiment directory, where users who have data access privileges can get to it.
BIAC's transd software is designed to run on GE Signa scanner, monitoring directories for k-space data and transferring raw data files off of the scanner via NFS mounts and/or SCP connections.
Note: This primarily describes Functional Data Flow once the data has been transferred off of the scanner and onto a valid processing server. Anatomical Data Flow is similar, only the set of processes applied to the input data differ.
For functional data, the Patient ID that is entered on the scanner console is primarily used for identification. Our software takes what is entered in on the console, strips out the punctuation, and lowercases all text before before comparing against a list of valid Experiments.
If you entered a period in the Patient ID field, GE's software seems to have a bug in which the characters following the period are truncated before being inserted into the raw data header. As a result, the truncated Patient ID is unrecognized and the image results gets transferred to the Salvage directories. This only applies to functional data from the 4.0T.
Under the 'Services' page on the BIAC website, click on 'Exam Tracker' and enter your 5 digit exam number. If the processing daemon has picked up and processed the files, you'll see the relevant log information.
If the error you see is 'Experiment Not Found', please submit a trouble ticket so our data administrators can know where the data was supposed to be sent. Our data admins will respond as soon as possible to the trouble ticket.
