[edit] XMLPipeDB Match Practice
- What Match command tallies the occurrences of the pattern GO:000916. in the 493.P_falciparum.xml file?
- 2 unique matches
- First match occurred twice, second match occured once.
- There appears to be multiple references to this in the doccument. It appears to be a specific alignment on a protein sequence of 493.P-Falciparum
- What Match command tallies the occurrences of the pattern \"James.*\" in the 493.P_falciparum.xml file?
- 2 Unique matches
- First match occurred 8238 times, second match occurred 1 time.
- When I typed in the command grep "\James.*\"", it told me that it was a persons name. By looking at the title and noticing the file is copyrighted, I believe that it is safe to assume that James K.D. is the name of an author of a scientific article.
- Use Match to count the occurrences of the pattern ATG in the hs_ref_GRCh37_chr19.fa file (this may take a while). Then, use grep and wc to do the same thing.
- Match brought back 830,101 matches
- grep and wc gave me 502,401 lines, 502,401 words and 35671048 letters
- It makes sense that grep and wc had less matches because they cannot account for multiple matches on the same line.
