15 DESCRIPTION
|
|
|
16 Merge multiple CSV or TSV *TextFiles* into first *TextFile* to generate
|
|
|
17 a single text file. Unless -k --keys option is used, data rows from
|
|
|
18 other *TextFiles* are added to first *TextFile* in a sequential order,
|
|
|
19 and the number of rows in first *TextFile* is used to determine how many
|
|
|
20 rows of data are added from other *TextFiles*.
|
|
|
21
|
|
|
22 Multiple *TextFiles* names are separated by space. The valid file
|
|
|
23 extensions are *.csv* and *.tsv* for comma/semicolon and tab delimited
|
|
|
24 text files respectively. All other file names are ignored. All the text
|
|
|
25 files in a current directory can be specified by **.csv*, **.tsv*, or
|
|
|
26 the current directory name. The --indelim option determines the format
|
|
|
27 of *TextFiles*. Any file which doesn't correspond to the format
|
|
|
28 indicated by --indelim option is ignored.
|

|
61 keys are specified by column numbers or labels for each text file
|
|
|
62 delimited by ";".
|
|
|
63
|
|
|
64 By default, data rows from text files are merged into first file in
|
|
|
65 the order they appear.
|
|
|
66

|
|
|
116 NewSample.csv, type:
|
|
|
117
|
|
|
118 % MergeTextFiles.pl -r NewSample -o Sample1.csv Sample2.csv
|
|
|

|
|
|
133 Sample3.csv
|
|

|
|
|
136 from Sample2.csv and Sample3.csv into Sample1.csv using "Mol_ID" as a
|
|
|
137 column keys starting after the last column and to generate
|
|
|
138 NewSample.tsv, type:
|
|
|
139
|
|
|
