Select Sequences and Functions
There are different functions for selecting and deselecting sequences. Most functions in Blast2GO are only applied to selected elements. Selections allow to create a subset or apply certain functions to parts of a given dataset.
Select Sequences (PRO Feature)
The Select Sequences feature can be applied to Blast2GO Projects only and allows to select sequences for many different criteria. Selections can be added to existing ones, subtracted or created from scratch.
- Sequence Name. This is a general function for (de)selecting sequences by loading a file containing a list sequence IDs.
- Sequence Description. Blast2GO allows to (de)select sequences according to Blast result description.
- Function (GO-Terms or GO-IDs). This is a general function for (de)selecting sequences by loading a file containing a list of GO-Terms or GO-IDs.
- InterProScan IDs.
- Enzyme IDs.

Select Sequence by Color
This function allows (de)selection of sequences on the basis of their color code i.e. the processing stage they have.
Figure 2: Selection by Color
Other Select Options
This function will invert the current selection. Those sequences that are not selected will now be selected and vice versa.
Delete Selected Sequences
This function will delete selected sequences from the Main Sequence Table
Extract Selection to New Tab (PRO feature)
One can extract a subset of the selected sequences to a new project.
Once one have the desired sequences selected it is possible to hide/filter out the deselected ones by clicking on the icon next to the selection checkbox on the table.
Figure 3: Show only selected sequences
With Ctrl+A in Windows/Linux or appleKey+A on Mac OS all selected sequences will be marked. Now right click on one of the sequences on the table and choose the 2nd option Extract Selection to New Tab.
Figure 4: Extract Selection to New Tab
A new project will be created of the selected sequences.
Export Selected Sequences as DAT
Once you have the desired sequences selected you can export these instead of saving the whole dataset. In order to do so go to File > Export > Legacy Format > Export Selected Sequences as DAT and browse for the folder you want to save.
