Alternative procedure for generating FASTA sequences


 

Alternative Method

by Ann Turner

 

Since I don't have access to the personal results pages, where the mutations are highlighted in red, I use the sequence at MitoMap.

 

For HVR1, I copy and paste the lines beginning with 16021 into a text editor.

(Very, very few HVR1 sequences will have mutations prior to 16024, which is where the "classical" HVR1 range begins.)

 

Then I use the numbers at the beginning of each line and count off the blocks of 10. For my mutation at 16293G I go to the line starting with 16261 and mumble to myself 16261-16271-16281-16291 to get to the block that would contain 16293. Then I count 16291-16292-16293 and replace the letter there (which happens to be an "a") with an upper-case G. The case does not matter at BLAST, so the upper case letter is sort of a flag for me.

 

The lines below also have my mutation at 16519C.

Then I copy-and-paste those lines (with no further editing to remove numbers and spaces) into the box at BLAST.
