The DragonOrder tool accepts sorted microarray data and displays the location of genes families on that sorted list. The idea behind the DragonOrder tool is similar to that of the DragonFamilies tool. That being that it is beneficial for the user to be able to rapidly identify groups of related genes that are co-expressed. The difference is that the DragonOrder tool automatically sorts the gene expression data set by ratio values during the analysis. The sorting allows DragonOrder to first identify all genes which are classified by a certain type of information and then map out where each of those genes in located on that sorted list. This form of information visualization allows for the identification of clusters of related, differentially regulated genes in the context of every gene on the supplied list. Clusters of related genes at either end of the list are potentially interesting.
Instructions and Example Data Sets
Before you start...
It is highly preferred if the data you use in either the uploaded or pasted form is comma-delimited, not tab-delimited. The easiest way to generate a comma-delimited text file is to save your data as a ".csv" file in MS Excel. Your data should be sorted by ratio expression values. View the example data sets below.

Example Data Set
EXAMPLE DATA SET: Left click on the link to the left in order to copy and paste, or right click on it, save it to your computer and then re-upload it with the upload feature below.

1) Paste your delimited text file in the proper format.
2) Specify the columns in which your three types of information are located.
3) Specify which sorts of delimiters you are using and then press "Analyze Data"
1) Paste your data in the field below.
Paste your data here.
2) Specify the columns in which your three types of information are located.
Indicate which columns contain your:
Expression values
, Genbank numbers , and Type values
3) Specify which sorts of delimiters you are using.
Text to use as field delimiter (Assumed "," if left blank. Don't use tab-delimited text files.):
Text to use as line delimiter (assumed "newline" if left blank):
I want to draw lines
