215 This tool imports a collection of genomic region datasets, and associates to each region
|
|
|
216 multiple genomic feature measurements. It allows to align the regions in multiple ways
|
|
|
217 (center, left, right or scale alignment), to smooth the feature curves (possibly filling gaps in the
|
|
|
218 measurements) and to create a graphical representation of the feature measurements in each
|
|
|
219 region datasets (aligned curves or pointwise quantile curves).

223 **Region datasets**
|
|
|
224
|
|
|
225 Each region dataset can be provided as a BED or Tabular file with tab delimited columns chr
|
|
|
226 start end (extra columns present in the input file are ignored). Regions can be of different
|
|
|
227 length::
|
|
|
228
|
|
|
229 chr2 49960150 50060150
|
|
|
230 chr2 55912445 56012445
|
|
|
231 ...
|
|
|
232
|
|

|
|
|
234
|
|
|
235 **Feature measurements**
|
|
|
236
|
|
|
237 Feature measurements corresponding to all the regions can be provided as a BED or Tabular
|
|
|
238 file with tab delimited columns chr start end value::
|
|
|
239
|
|
|
240 chr2 49960150 49962150 0.9426
|
|
|
241 chr2 49962150 49964150 0.7816
|
|
|
242 ...
|
|
|
243
|
|
|
244 Each feature must be measured in windows of a fixed size inside all the regions (missing
|
|
|
245 values must be indicated as NA). Another way to import feature measurements is from a
|
|
|
246 Tabular file with the first three columns chr start end corresponding to the different genomic
|
|
|
247 regions, followed on the same row by all the measurements in fixed-size windows::
|
|
|
248
|
|
|
249 chr2 49960150 50060150 0.9426 0.7816 0.8921 ... ... 1.2063
|
|
|
250 chr2 55912445 56012445 0.8719 0.9975 1.1619 ... ... 0.9601

255 **Output**
|
|
|
256
|
|
|
257 The tool returns:
|
|
|
258
|
|
|
259 1. RData with the IWTomicsData object, that stores the aligned genomic region datasets, and their associated feature measurements;
|
|
|
260 2. Region dataset identifiers;
|
|
|
261 3. Feature identifiers;
|
|
|
262 4. PDF file with the plotted data.
|
|
|
263
|
|
|
264 1-3 can be used as input of the tool *IWTomics Test and Plot*

272 This Galaxy tool has been developed by Fabio Cumbo (Third University of Rome, Italy) and Marzia A. Cremona (The Pennsylvania State University, USA).
|
|
|
273
|
|
|
274 It implements a simplified version of the methods *smooth* and *plot* for *IWTomicsData* objects.
|
|
|
275 The complete version can be found in the *R/Bioconductor* package *IWTomics* (see vignette_).
