Download An Excel Macro to Visualise Patterns for Chosen Genes

My Excel Macro
Based on macro by Frank Millenaar (Utrecht)
Selects genes of interest from Mas5 output spreadsheet
Visualises expression profiles as combined:
data-tables
heat-maps
Can adapt for different combinations of chips to give different profiles
Eg a range of organs.
Similar in function to GenevestigATor
….but email me if you want to have a go.

Unformatted NASCAffy (MAS5) output
– All 23,000 genes from ATH1 chip
– For each gene

For each array
– Signal value
– Detection Call
– Detection P Value
• Each replicate chip is separate (3) columns
– IE to much data for a human mind to see patterns!
List of genes of interest
output
Data for our chosen genes only
Can use different chip sets
– e.g. organs
– e.g. treatments
genes
Replicate chips can be

For each gene, only:
