281 **Hammock overview**
|
|
|
282
|
|
|
283 Hammock performs peptide sequence clustering. It is able to identify clusters of sequences sharing a sequence motif within big datasets. For news, documentation and other available versions, see http://www.recamo.cz/en/software/hammock-cluster-peptides/

298 Hammock accepts fasta files. For basic work, fasta description lines (those starting with ">") may contain virtually anything. For work with the concept of sequence labels, description line should be in this form:
|
|
|
299
|
|
|
300 | >id|count|label
|
|
|
301
|
|
|
302 an example of two records in this format:
|
|
|
303
|
|
|
304 | >1|42|label1
|
|
|
305 | RSPIVRQLPSLP
|
|
|
306 | >2|58|label2
|
|
|
307 | GSWVVDISNVED
|
|
|
308
|
|
|
309 For more detailed description of the label concept and input format, see the documentation_.

313 **Outputs**
|
|
|
314
|
|
|
315 Hammock returns two files, both are semicolon-separated tables.
|
|
|
316
|
|
|
317 The first is the cluster overview file. It contains one line for each resulting cluster plus header. Columns are:
|
|
|
318
|
|
|
319 cluster_id main_sequence sum label1 label2 label3 ...
|
|
|
320
|
|
|
321 | cluster_id: Cluster's unique numeric identifier.
|
|
|
322 | main_sequence: The most popular (appearing in the highest number of copies) sequence of this cluster
|
|
|
323 | sum: Total count of all sequences in this cluster (sum over all labels)
|
|
|
324 | label1, label2 etc. Counts of sequences with particular labels
|
|
|
325
|
|
|
326
|
|
|
327 The second file provides more detailed information. It contains one line for each clustered sequence plus header. Columns are:
|
|
|
328
|
|
|
329 cluster_id sequence alignment sum label1 label2 label3 ...
|
|
|
330
|
|
|
331 | cluster_id: Id of the cluster this sequence belongs to
|
|
|
332 | sequence: Amino acid sequence of this peptide
|
|
|
333 | alignment: Aligned amino acid sequence of this peptide (part of cluster's multiple sequence alignment)
|
|
|
334 | sum: Total count of copies of this sequence (sum over all labels)
|
|
|
335 | label1, label2 etc. Counts of copies with particular labels
|
|

339 **Parameters**
|
|
|
340 Default and auto-detected parameters have been carefully tuned and tested to work well with several datasets, they are especially suited for short peptides from Phage display experiments. Neverheless, there is no such thing as universal rules suitable for every dataset - parameter understanding and tuning may be needed. For more detailed description of parameters, see the documentation_.
