An annotation file is a tab-delimited text file containing annotation data for a mev files. The ExpressConverter extracts the useful information from an input file and converts it to
mev format. At the same time, it writes the annotation information to an annotation file. The annotation file name is automatically produced using the same name of the input file with different extension
.ann. The association between the
mev and the annotation files is set up by the unique id defined in the
mev file. The comment of the
.ann file is the same as that in
mev file and the first three columns are:
| UID: | Unique identifier for this spot. |
|---|
| R: | Row (slide_row). |
|---|
| C: | Column (slide column). |
|---|
If you have a set of files that were generated with the same array design method, the annotation of each spot for the files should be the same. Thus, you can produce only one annotation file for the set of mev files by checking the
Many to One under the
Ann File menu.
