Array Server provides a simple way to allow users to register, annotate and manage the samples through one one-click submission of a text file. Sample registration is limited to the LabManager user group or higher.
Below is a sample input file for sample registration:
User can get this text file from downloaded tutorial data.
The input file has one required section and one optional section:
Samples: this required section lists samples, associated file path, and meta data for the samples. Fields are tab delimited. First row must be column headers, and the first two columns must be SampleID and FilePath. SampleID must be unique across the full database, and FilePath must be a relative path that s exposed by the Array Server FTP server (usually it points to a mapped folder). Multiple files, separated by "|", can be specified for each sample. The user can contain as many additional columns (e.g. LIMS fields, treatments and other grouping information, etc.) as needed, but it is recommended to control the vocabulary for both the column name and column value.
Depending on server configurations, certain columns in your input file are set to MANDATORY. These settings can be viewed by the server administrator under Manage | Server Information | Show Sample Template. This will open a Table where users can see which columns are needed in the Samples section. Please check this setting and, if necessary, add mandatory columns to the table provided with this tutorial.
ArraySuite supports multiple file types in FilePath, including CEL, FASTQ, BAM and etc. For more details, please read the following wiki page: link
SampleSet: this section is optional and lists the meta data for the sample set that will be automatically generated based on the listed samples in the Samples section. The user can set Editor and Reader for the sample set but these two fields are not required.
