It selects the head of a sequence file. But instead of working text line by text line as the standard Unix tool, selection is done at the sequence record level. You can specify the number of sequence records to select. .INDENT 0.0 .INDENT 3.5 \fIExample:\fP .INDENT 0.0 .INDENT 3.5 .INDENT 0.0 .INDENT 3.5 .sp .nf .ft C > obihead \-n 150 seq1.fasta > seq2.fasta .ft P .fi .UNINDENT .UNINDENT .sp Selects the 150 first sequence records from the \fBseq1.fasta\fP file and stores them into the \fBseq2.fasta\fP file. .UNINDENT .UNINDENT .UNINDENT .UNINDENT .SH OBIHEAD SPECIFIC OPTIONS .INDENT 0.0 .TP .B \-n , \-\-sequence\-count= Number of sequence records to be selected (default value : 10). .UNINDENT .SH OPTIONS TO SPECIFY INPUT FORMAT .SS Restrict the analysis to a sub\-part of the input file .INDENT 0.0 .TP .B \-\-skip The N first sequence records of the file are discarded from the analysis and not reported to the output file .UNINDENT .INDENT 0.0 .TP .B \-\-only Only the N next sequence records of the file are analyzed. The following sequences in the file are neither analyzed, neither reported to the output file. This option can be used conjointly with the \fI–skip\fP option. .UNINDENT .SS Sequence annotated format .INDENT 0.0 .TP .B \-\-genbank Input file is in genbank format. .UNINDENT .INDENT 0.0 .TP .B \-\-embl Input file is in embl format. .UNINDENT .SS fasta related format .INDENT 0.0 .TP .B \-\-fasta Input file is in fasta format (including OBITools fasta extensions). .UNINDENT .SS fastq related format .INDENT 0.0 .TP .B \-\-sanger Input file is in Sanger fastq format (standard fastq used by HiSeq/MiSeq sequencers). .UNINDENT .INDENT 0.0 .TP .B \-\-solexa Input file is in fastq format produced by Solexa (Ga IIx) sequencers. .UNINDENT .SS ecoPCR related format .INDENT 0.0 .TP .B \-\-ecopcr Input file is in ecoPCR format. .UNINDENT .INDENT 0.0 .TP .B \-\-ecopcrdb Input is an ecoPCR database. .UNINDENT .SS Specifying the sequence type .INDENT 0.0 .TP .B \-\-nuc Input file contains nucleic sequences. .UNINDENT .INDENT 0.0 .TP .B \-\-prot Input file contains protein sequences. .UNINDENT .SH COMMON OPTIONS .INDENT 0.0 .TP .B \-h, \-\-help Shows this help message and exits. .UNINDENT .INDENT 0.0 .TP .B \-\-DEBUG Sets logging in debug mode. .UNINDENT .SH AUTHOR The OBITools Development Team - LECA .SH COPYRIGHT 2019 - 2015, OBITool Development Team .\" Generated by docutils manpage writer. .
