How to delete in a table a row which contains a specific word

31 views (last 30 days)
Hello, I'm writing to you for this particular modification of my table that I extracted from a long .csv file using the function readtable
I have a very big table of data 56644x8 (some colums are number/coordinates, others contain words).
I'm interested to eliminate the rows which contain the word "Alignment" at the 7th column.
The more difficult step is that I would create a code that recognize words like Allignment, Allignment_test, Alignment_ecc, Alignment2 because I don't know if the input data could change in the future.
I'll appreciate all type of helps, thank you very much
Andrea
Edit: I attached a similar file to mine, hope it will be helpful

try with this:
A=readtable('andrea_file.csv','ReadVariableNames',false,'HeaderLines',3);
B=table2cell(A);
C=string(B)
C = 2×8 string array
"R" "-0.9" "-94.8" "-9.5" "-2" "-45" "Another_text_i_want_to mantain" "1" "R" "0.5" "5" "-2" "3" "0" "Alignment_Pin" "2"
[row col]=find(C=='Alignment_Pin');
C(row,:)=[]; % eleminating row that contains "Alignment_Pin"
C(:,[2 3])=[] % eleminating column 2 and 3
C = 1×6 string array
"R" "-9.5" "-2" "-45" "Another_text_i_want_to mantain" "1"

as you did not attach your file, i have attached my own created data
A=readtable('myfile.xlsx','ReadVariableNames',false);
B=table2array(A);
C=string(B);
[row col]=find(C=='Alignment');
C(row,:)=[];

Error using table2array (line 37)
Unable to concatenate the table variables 'Var1' and 'Var2', because their types are cell and double.
Error in Import_Matrix_status (line 5)
B=table2array(A);
Hi, using that code fives me this (the same) error.. I think the problematic is the command "table2array" that is not permitted..Maybe I can work directly on the table A to elimate row bypassing B?
Thanks
