Question: How can I handle 5 different time series gene expression pattern for the yeast gene SAM3 to infer gene functions for similarities between microarray time series gene expression patterns?

I am trying to infer gene functions from similarities and dissimilarities between the trajectories between the expression trajectories of genes.

To trust my results I must understand why I am getting five different expression patterns for the yeast gene with the common name "SAM3".

I tried in vain to find the nucleotide gene sequences for the 5 different SAM3 expression pattern. Their prob-set IDs are






The information in each of the 5 lines is identical, except for the last line, which also lists the systematic name of SAM3. How can I chose the correct expression pattern from these 5 possible options? What's the reason that generated these 5 options?

The platform / chip of this dataset is

GPL90 [YG_S98] Affymetrix Yeast Genome S98 Array

Thanks a lot
