121 Data normalization must be run with the Data Normalization tool prior to SNPs selection. Otherwise, the standalone version can be used to perform marker selection from matrices containing data normalized with tools different from the one proposed in this instance.

125 **What it does**
|
|
|
126
|
|
|
127 This tool selects some relevant markers according to a response using penalized regressions.
|
|
|
128
|
|
|
129 Output:
|
|
|
130
|
|
|
131 A tabular text file containing 5 columns which describe all the selected SNPs (1 line per SNPs):
|
|
|
132
|
|
|
133 - chr: Chromosome containing the selected SNP.
|
|
|
134 - position: Position of the selected SNP.
|
|
|
135 - index: Index of the selected SNP.
|
|
|
136 - names: Name of the selected SNP.
|
|
|
137 - coefficient: Regression coefficient of the selected SNP.
|
|
|

|
141 **Data Response csv file**
|
|
|
142
|
|
|
143 Data response csv file format:
|
|
|
144
|
|
|
145 - The first column contains the names of the different files of the data-set.
|
|
|
146
|
|
|
147 - The second column contains the response associated with each file.
|
|
|
148
|
|
|
149 - Column names of these two columns are respectively files and response.
|
|
|
150
|
|
|
151 - Columns are separated by a comma
|
|
|
152
|
|
|
153 - *Extensions of the files (.CEL for example) should be removed*
|
|
|
154
|
|
|
155
|
|
|
156
|
|
|
157 **Example**
|
|
|
158
|
|
|
159 Let 3 .cel files in the studied dataset ::
|
|
|
160
|
|
|
161 patient1.cel
|
|
|
162 patient2.cel
|
|
|
163 patient3.cel
|
|
|
164
|
|
|
165 The csv file should look like this ::
|
|
|
166
|
|
|
167 files,response
|
|
|
168 patient1,1.92145
|
|
|
169 patient2,2.12481
|
|
|
170 patient3,1.23545

|
|
|
174
|
|
|
175 **Normal-tumor study**
|
|
|
176
|
|
|
177 In cases where normal (control) samples match to tumor samples, they are taken as references to extract copy number profile. In this case, a normal-tumor csv file must be provided :
|
|
|
178
|
|
|
179 - The first column contains the names of the files corresponding to normal samples of the dataset.
|
|
|
180
|
|
|
181 - The second column contains the names of the tumor samples files.
|
|
|
182
|
|
|
183 - Column names of these two columns are respectively normal and tumor.
|
|
|
184
|
|
|
185 - Columns are separated by a comma.
|
|
|
186
|
|
|
187 - *Extensions of the files (.CEL for example) should be removed*
|
|
|
188
|
|
|
189
|
|
|
190 **Example**
|
|
|
191
|
|
|
192 Let 6 .cel files in the studied dataset (3 patients, each of them being represented by a couple of normal and tumor cel file.) ::
|
|
|
193
|
|
|
194 patient1_normal.cel
|
|
|
195 patient1_tumor.cel
|
|
|
196 patient2_normal.cel
|
|
|
197 patient2_tumor.cel
|
|
|
198 patient3_normal.cel
|
|
|
199 patient3_tumor.cel
|
|
|
200
|
|
|
201
|
|
|
202 The csv file should look like this ::
|
|
|
203
|
|
|
204 normal,tumor
|
|
|
205 patient1_normal,patient1_tumor
|
|
|
206 patient2_normal,patient2_tumor
|
|
|
207 patient3_normal,patient3_tumor
