| 269 | 1 : Choose your inputs | zip | | |
| 270 +---------------------------+------------+ | |
| 271 | |
| 272 **Choose your inputs** | |
| 273 | |
| 274 You have two methods for your inputs: | |
| 275 | |
| 276 | Zip file (recommended): You can put a zip file containing your inputs: myinputs.zip (containing all your conditions as sub-directories). | |
| 277 | library folder: You must specify the name of your "library" (folder) created within your space project (for example: /projet/externe/institut/login/galaxylibrary/yourlibrary). Your library must contain all your conditions as sub-directories. | |
| 278 | |
| 279 Steps for creating the zip file | |
| 280 ------------------------------- | |
| 281 | |
| 282 **Step1: Creating your directory and hierarchize the subdirectories** | |
| 283 | |
| 284 | |
| 285 VERY IMPORTANT: If you zip your files under Windows, you must use the 7Zip software (http://www.7-zip.org/), otherwise your zip will not be well unzipped on the platform W4M (zip corrupted bug). | |
| 286 | |
| 287 Your zip should contain all your conditions as sub-directories. For example, two conditions (mutant and wild): | |
| 288 arabidopsis/wild/01.raw | |
| 289 arabidopsis/mutant/01.raw | |
| 290 | |
| 291 **Step2: Creating a zip file** | |
| 292 | |
| 293 Create your zip file (e.g.: arabidopsis.zip). | |
| 294 | |
| 295 **Step 3 : Uploading it to our Galaxy server** | |
| 296 | |
| 297 If your zip file is less than 2Gb, you get use the Get Data tool to upload it. | |

| 303 Advices for converting your files for the XCMS input | |
| 304 ---------------------------------------------------- | |
| 305 | |
| 306 We recommend you to convert your raw files to **mzXML** in centroid mode (smaller files) and the files will be compatible with the xmcs centWave method. | |
| 307 | |
| 308 **We recommend you the following parameters:** | |
| 309 | |
| 310 Use Filtering: **True** | |
| 311 | |
| 312 Use Peak Picking: **True** | |
| 313 | |
| 314 Peak Peaking -Apply to MS Levels: **All Levels (1-)** : Centroid Mode | |
| 315 | |
| 316 Use zlib: **64** | |
| 317 | |
| 318 Binary Encoding: **64** | |
| 319 | |
| 320 m/z Encoding: **64** | |
| 321 | |
| 322 Intensity Encoding: **64** | |

| 332 **Matched Filter** | 197 **PeakDensity** |
| 333 | 198 |
| 334 | One parameter to consider is the Gaussian model peak width used for matched filtration,an integral part of the peak detection algorithm. | 199 | This method performs performs correspondence (chromatographic peak grouping) based on the density (distribution) of identified peaks along the retention time axis within slices of overlapping mz ranges. All peaks (from the same or from different samples) being close on the retention time axis are grouped into a feature (peak group). |
| 335 | For a discussion of how model peak width affects the signal to noise ratio, see Danielsson et al. (2002). | 200 | See the PeakDensity_manual_ |

| 338 **cent Wave** | 203 .. _PeakDensity_manual: https://rdrr.io/bioc/xcms/man/groupChromPeaks-density.html#heading-2 |
| 339 | 204 |
| 340 | This algorithm is most suitable for high resolution LC/{TOF,OrbiTrap,FTICR}-MS data in centroid mode. | 205 |
| 341 | Due to the fact that peak centroids are used, a binning step is not necessary. | 206 Method to use for adjustRtime |
| 342 | The method is capable of detecting close-by-peaks and also overlapping peaks. Some efforts are made to detect the exact peak boundaries to get precise peak integrals. | 207 ------------------------------------------- |
| 343 | 208 |
| 344 | 209 **PeakGroups** |
| 345 ------------ | 210 |
| 346 Output files | 211 | This method performs retention time adjustment based on the alignment of chromatographic peak groups present in all/most samples (hence corresponding to house keeping compounds). First the retention time deviation of these peak groups is described by fitting either a polynomial (‘smooth = "loess"’) or a linear ( ‘smooth = "linear"’) model to the data points. These models are subsequently used to adjust the retention time of each spectrum in each sample. |

| 349 IPO_parameters4xcmsSet.tsv | 214 **Obiwarp** |
| 350 | 215 |
| 351 | Optimal parameters for xcmsSet | 216 | This method performs retention time adjustment using the Obiwarp method [Prince 2006]. It is based on the code at http://obi-warp.sourceforge.net but supports alignment of multiple samples by aligning each against a _center_ sample. The alignment is performed directly on the ‘profile-matrix’ and can hence be performed independently of the peak detection or peak grouping. |
