NBTdatabase

NBT uses the NBTdatabase to store meta data. This data is used in, e.g., the analysis and visualization tools to display correct legends.

The NBTdatabase consists of nbt_Info objects.

Structure

The NBTdatabase is build as an relational database with nbt_Info.ProjectID, nbt_Info.SubjectID, and nbt_Info.Condition as primary keys.

Meta data exists on four levels:

Project
nbt_Info object stored in ProjectInfo.mat

with this information

  • Project ID
  • Project description
  • Researcher ID
  • Description of Conditions

Subject
nbt_Info object stored in each Subject folder in the SubjectInfo.mat or if more convenient in each _info file.

Properties

  • subject_gender
  • subject_age
  • subject_headsize
  • subject_handedness
  • subject_medication
  • notes
  • Session log

The subject meta information is bound to the project information via the nbt_Info.ProjectID field.

Signal
For each signal a corresponding _info file is stored with meta data. This file is bound to the Subject via the nbt_Info.SubjectID field, and condition via the nbt_Info.ProjectID and ConditionID.

How to delete all nbt_info objects

You can delete all nbt_info files (i.e your whole NBTdatabase) using the nbt_DeleteInfoFiles.

GUI

The NBTdatabase has a GUI, which can be used either from the NBT GUI menu Database tool|NBTdatabase, or by the command nbt_NBTdb

The NBTdatabase GUI has a build-in logbook function.
