Issues accessing different recordings with Session in matlab

Hi

I'm trying to analyze OE data with matlab. From an experiment, I have two recordings. So when I load data with the Session function:
session=Session(directory)

I can see two recordings:
session.recordNodes{1}
format: 'Binary'
recordings: {[1×1 BinaryRecording] [1×1 BinaryRecording]}

However, data from both recordings{1} and recordings{2} are the same (whether I look at continuous or ttlEvents). I guess it's something stupid I don't see but I'm stuck here. Any help would be really appreciated.

Error using containers.Map/subsref

Hi
I'm recording with OE gui v0.6.3
when tryin to load a recording with 2 record nodes i get this error:

"specified key not present"

Hi,
When I try to load data that was recorded using the new GUI (v.0.6.0) into Matlab, I encounter the following error:
-I set my directory
-I enter season = Session(directory)
-But then I receive an error:
"Error using containers.Map/subsref
The specified key is not present in this container."
Thanks for any help or ideas!

Incorrect processorId value in BinaryRecording.m

Hi,
I get this error when opening a recording session with session = Session(directory) - using code v1.0.0 with Matlab 2022b:

Error using  * 
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second
matrix. To operate on each element of the matrix individually, use TIMES (.*) for elementwise multiplication.

Error in BinaryRecording/loadEvents (line 128)
                self.ttlEvents(id) = DataFrame(abs(lines), sampleNumbers, timestamps, processorId*ones(numEvents,1), repmat(string(id),numEvents,1), lines > 0, ...

Error in BinaryRecording (line 41)
            self = self.loadEvents();

Error in BinaryRecording.detectRecordings (line 254)
                    recordings{end+1} = BinaryRecording(recordingDirectories{recIdx}, expIdx, recIdx);

Error in RecordNode/detectRecordings (line 95)
                self.recordings = BinaryRecording.detectRecordings(self.directory);

Error in RecordNode (line 71)
            self.detectRecordings();

Error in Session/detectRecordNodes (line 70)
                self.recordNodes{end+1} = RecordNode(paths{i});

Error in Session (line 61)
            self.detectRecordNodes();

The processorId variable is empty, from its definition at line 117.
At this stage, fullId's value is 1×2 cell array {'DAQmx-109'} {'PXIe-6341'}, which leads str2num to return an empty value.
What is the expected behavior of processorId = str2num(fullId{1}); on line 117 ?

Running into errors when running "session"

I'm running into errors trying to run the session command. I need some guidance to learn how to use this matlab package. Any help would be appreciated.
