  • Select the annotation file; we have selected in this example, we select a .pannot file downloaded from Partek distributed library file repository (www.partek.com/html/libIndex.txt) – hg19_refseq_14_01_03_v2.pannot from the C:/Microarry Libraries folder
  • Delete or rearrange the columns as necessary; we have placed the column with identifiers (should be unique ID) that correspond to our gene list first
  • Select File then Save As Text File... to save the annotation file; we have named it Annotation File (Figure 2)

The annotation file has been associated with the spreadsheet and additional tasks can now be performed on the data, e.g. since the annotation has genomic location, you can draw chromosome view on this data.

Annotating with cytobands

  • Select Annotate with Cytobands from Tools in the main toolbar when a suitable spreadsheet is open

A column with cytoband locations will be added to the spreadsheet. Adding a cytoband is possible if genomic coordinates are associated with the gene list spreadsheet. 

Annotating with known SNPs

  • Select Annotate with Known SNPs... from Tools in the main toolbar when a suitable spreadsheet is open

A column of SNPs associated the listed genes and a column indicating the number of SNPs known to be associated with the genes will be added to the spreadsheet. If a SNP database has not been previously downloaded, it will need to be downloaded through the SNP database dialog (Figure 8).

Alternatively, to generate a list of SNP IDs per row, right-click on a row header and select Create list of dbSNP.

In addition to SNPs, this feature can associate any data with a list of genes or genomic coordinates; the dbSNP database, any miRNA database, data from the Database of Genomic Variants (dgv), any mRNA transcriptome database, or any custom annotation source can be associated with your list. In each case, this feature will add columns to the imported gene list spreadsheet that match the genes with features from those databases.
