Dear all,


I have my data in ".set" format, in order to load it into NBT, I followd
the tutorial information:

Importing data into NBT formatIntroduction: The NBT file format
 In order to use the scripts from NBT in the most efficient way, you need
to convert your data into the NBT file format. This file format insures
that information about your recording can easily be read by the NBT
functions.  The NBT signal file format consists of two files; the Signal
and Info file. These files are named after the NBT file name definition:
<ProjectID>.<SubjectID>.<Date of recording>.<Condition>  e.g.,
NBT.S0099.20090212.EOR2.  If this information is not available, you will
still have to add dummy information, e.g., YYYYMMDD instead of the actual
date. E.g., NBT.S0099.YYYYMMDD.EOR2.  The signal data is stored in a NBT
Signal file (.mat format), that contains a Signal matrix called Signal, in
which each column represents a signal from one channel.  Information about
the signal is stored in the NBT Info file (.mat format) that contains an
NBT Info object. The NBT Info file has the same name as the NBT Signal
file, extended with _info, for example NBT.S0099.20090212.EOR2_info. This
file contains an NBT Info object called SignalInfo (see nbt_Info.m for
definition). The original name of your file is stored in this object, in
the field Info.interface.original_file_name.  The reason for this separate
Info file is to be able to quickly access and add information. If the Info
file would be in the same file as the signal data, then every time you
would like to add new information, you would have to resave the complete
data file, which may take a long time if the signals are long (this is an
unfortunate property of Matlab).

*Is this a correct way to covert my data into NBT format?*

Now I have my data as the attached photo,  and I need to compute the
"Spectral biomarkers" from "Compute biomarkers"menu; knowing that I
selected "CLEANSignal" because my data that are form".set" format were
aalready preprocess and cleaned using EEGLAB,

then I convert it into NBT applying the process I explained at begining.
After doing so, I had this result in Matlab command window:

NB: I had same error message in  Signal and  ICASignal


*How to solve this problem?*
