259 =head1 NAME
260
261 TextFilesToSDFiles.pl - Generate SD files from CSV or TSV TextFile(s)
262
263 =head1 SYNOPSIS
264
265 TextFilesToSDFiles.pl TextFile(s)...
266
267 TextFilesToSDFiles.pl [B<-h, --help>] [B<--indelim> comma | semicolon] [B<-l, --label> yes | no]
268 [B<-o, --overwrite>] [B<-r, --root> rootname] [B<-w, --workingdir> dirname] TextFile(s)...
269
270 =head1 DESCRIPTION
271
272 Generate SD files from CSV or TSV I<TextFile(s)>. The new SD files contain no structure data
273 as indicated by empty structure data block; Data fields and values in SD files are generated
274 using I<TextFile(s)> column labels and corresponding data values.
275
276 Multiple I<TextFile(s)> names are separated by space. The valid file extensions are
277 I<.csv> and I<.tsv> for comma/semicolon and tab delimited text files respectively.
278 All other file names are ignored. All the text files in a current directory can be specified
279 by I<*.csv>, I<*.tsv>, or the current directory name. The B<--indelim> option
280 determines the format of I<TextFile(s)>. Any file which doesn't correspond to
281 the format indicated by B<--indelim> option is ignored.
282
283 =head1 OPTIONS
284
285 =over 4
286
287 =item B<-h, --help>
288
289 Print this help message.
290
291 =item B<--indelim> I<comma | semicolon>
292
293 Input delimiter for CSV I<TextFile(s)>. Possible values: I<comma or semicolon>.
294 Default value: I<comma>. For TSV files, this option is ignored and I<tab> is used as a
295 delimiter.
296
297 =item B<-l, --label> I<yes | no>
298
299 First line contains column labels. Possible values: I<yes or no>. Default value: I<yes>.
300 Column labels are used to create SD data field labels; otherwise, data field labels look
301 like Column<colnumber>Data.
302
303 =item B<-o, --overwrite>
304
305 Overwrite existing files.
306
307 =item B<-r, --root> I<rootname>
308
309 New SD file names are generated using the root: <Root>.sdf. Default new file names:
310 <TextFileName>WithNoStrData.sdf. This option is ignored for multiple input files.
311
312 =item B<-w, --workingdir> I<dirname>
313
314 Location of working directory. Default: current directory.

318 =head1 EXAMPLES
319
320 To generate NewSample1.sdf file from Sample1.csv file, type:
321
322 % TextFilesToSDFiles.pl -o -r NewSample1 Sample1.csv
323
324 To generate NewSample1.sdf file from Sample1.tsv file which doesn't
325 contain column labels line, type:
326
327 % TextFilesToSDFiles.pl --label no -o -r NewSample1 Sample1.tsv
