I am having a file that looks like this:
PEBP1_HUMAN Homo sapiens P30086 PDB; 1BD9; X-ray; 2.05 A; A/B=1-187.
PDB; 1BEH; X-ray; 1.75 A; A/B=1-187.
PDB; 2L7W; NMR; -; A=1-187.
PDB; 2QYQ; X-ray; 1.95 A; A=1-187.
PECA1_HUMAN Homo sapiens P16284 PDB; 2KY5; NMR; -; A=686-738.
PDB; 5C14; X-ray; 2.80 A; A/B=28-229.
PDB; 5GEM; X-ray; 3.01 A; A/B=28-232.
PELO_HUMAN Homo sapiens Q9BRX2 PDB; 1X52; NMR; -; A=261-371.
PDB; 5EO3; X-ray; 2.60 A; A/B=265-385.
PDB; 5LZW; EM; 3.53 A; ii=1-385.
PDB; 5LZX; EM; 3.67 A; ii=1-385.
PDB; 5LZY; EM; 3.99 A; ii=1-385.
PDB; 5LZZ; EM; 3.47 A; ii=1-385.
From this file I want to match all EM;
elements that are found just after PDB; (four letter code); EM;
. So under this column either X-ray;
, NMR;
or EM;
can be found. For those lines that have EM;
remove them. Is there some bash command that I can use to match these elements and remove these lines?
Importantly when matching it put the space before EM
, so match it with space, like EM;
.
Expected result is:
PEBP1_HUMAN Homo sapiens P30086 PDB; 1BD9; X-ray; 2.05 A; A/B=1-187.
