Please follow the steps below to import the pre-normalized data:
Create a custom technology with the data file from:
GeneSpring Menu Bar → Annotations → Create Technology → Custom From File
Once the technology is created, please create a new experiment with those files to import into GeneSPring.
While creating an experiment, please choose the Experiment type as 'Generic Single color'.
In step 2 of 4, please check the option 'Please select if your data is in log scale' and the Normalization algorithm as 'None'.
In step 4 of 4, choose the option 'Do not perform baseline transformation'.
Now, the experiment is created with the pre-normalized data.
