In Land Configuration
Specify the virtual (relative to the folder mapping specified in [Folder] section in ArrayServer.cfg) path to Bas file folders. DNA-Seq or Exome-Seq BAS file will be loaded into genome browser on demand based on BamFileName_DnaSeq in the land meta data.
If all the bas files are saved in the same folder, users can define this folder as DnaSeqBasFolder and make the BasFileName_DnaSeq column only contain the bas file name for each sample. If bas files are saved in different folders, users have to set DnaSeqBasFolder to blank and make the BasFileName_DnaSeq column contain the full path of the bas file for each sample.
Administrator can control the BAS file read access through the Manage Users on the user group of mapped folder.
