<div class="">When I load a data set, the rank of the data is 58, the same as the number of channels.</div>
<div class="">Making no changes and saving the data set with another name, the rank changes to 1.</div>
<div class="">I like saving data at various check points while preprocessing, and this change in rank can affect specifying rank for the pca option to ica, or pcakeep to AMICA.</div>
<div class="">
<div class="">Any ideas?</div>
