+    \- **Samples to cluster** when clustering is performed on generic data, user have to select the columns to consider in clustering (first column, containing gene identifiers, will be automatically selected).

+
+\- **Genes filtering** can be applied before or after clustering step.
+
+- **Filtering before clustering** allows to restrict clustering to differentially expressed genes using differential analysis results (available for expression data and differential results clustering) or any generic file (available for generic data clustering). As an alternative, a specific gene list file can be directly used for filtering.
+
+- **Filtering after clustering** will have no effect on clustering or generated heatmaps. This filter is only applied to generated tabular files to keep differentially expressed genes (using differential analysis file or any generic file) or specific user defined genes (using gene list file). 
+
+\- **Filter approaches** : three filtering strategies can be applied before/after clustering depending on the nature of clustered data. These strategies use : differential analysis results (available for expression data and differential results clustering), generic file content (available for generic data clustering) or a gene list file (available for any input data).
+
+- **From differential analysis results** to filter genes based on fold change and FDR p-val for selected comparisons.
+
+    \- **Differential expression results file** is requested only for expression data clustering. For differential results clustering, the same differential results file selected as "data to cluster" is used. (see "Data to cluster section" for requested format)
+
+    \- **Comparisons to use** are requested only for expression data clustering. For differential results clustering, the same comparisons selected in "data to cluster" section will be used. If several comparisons are selected, genes that satisfy both fold change and FDR p-val thresholds in at least one of these comparisons are kept. 
+
+    \- **Fold change threshold** to use for filtering, genes with fold change >= threshold or fold change <= 1/threshold will be kept (set this threshold to 1 if you do not want to filter on fold change).
+
+    \- **FDR p-val threshold** to use for filtering, genes with FDR p-val <= threshold will be kept (set this threshold to 1 if you do not want to filter on FDR p-val).
+
+
+- **From generic tabular file** to filter genes based on selected columns values.
+
+    \- **Generic tabular file** contains gene in the first column and various informations used for filtering in the following (same format as clustered generic tabular file).
+
+    \- **Low filtering columns** used to discard rows with values below a given threshold (typically for Fold Change filtering). If several columns are selected, rows satisfying threshold condition in at least one of these columns are kept. 
+
+    \- **Low filtering threshold** below which the rows are discarded, the same threshold is applied for all selected columns.
+
+    \- **High filtering columns** used to discard rows with values above a given threshold (typically for p-value filtering). If several columns are selected, rows satisfying threshold condition in at least one of these columns are kept. 
+
+    \- **High filtering threshold** above which the rows are discarded, the same threshold is applied for all selected columns.
+
+- **From list of genes** to focus on pre-identified genes.
+
+    \- **Gene list file** with genes identifiers as one column file without header.

+
+-----
+
+**Advanced parameters**
+
+\- **Genes cluster number** used by hierarchical clustering (minimum is 2). See generated screeplot to adjust this number before re-running a clustering.
+
+\- **Samples/comparisons clusters number** used by hierarchical clustering applied on columns/conditions. Set to 1 (ie. no clustering) if you need to conserve input columns order for visualization purposes. Columns clusters information is not included (yet) in output tabular file.
+
+\- **Mathematical transformation** can be applied to clustered data before clustering and visualization. Data used for the filtering step are not modified by this transformation.
+
+\- **Distance measure** used to cluster rows and columns.
+
+\- **Agglomeration method** used to cluster rows and columns.
+
+\- **Add side bar** to vizualize factor values for displayed columns/conditions, represented as a colored side bar in the heatmap.
+
+- **Factor file** that contains factor information for coloring (same format as the factor file used for input data columns reordering).
+
+- **Factor to use** to color side bar depending on its values for displayed columns/conditions.
+
+- **Color palette used** for coloring factor values (see RColorBrewer R package documentation for more information on proposed palettes).
+
+\- **Maximum gene number** : for readability and running time considerations only, number of displayed rows (genes) in heatmaps/circular plot can be limited. Clustering information in generated tabular file and scree plot are computed from a global clustering considering all genes (excepting those filtered out before clustering). Heatmap and circular plot are displayed for a random gene selection, to avoid such random selection we advise you to use input filtering option before clustering to have a gene number below this limit.
+
+\- **Personalized heatmap colors** to build color gradient choosing start, middle and end colors.
+
+\- **Output format** for circular plots only.
+
+\- **Html snapshot format** for interactive plotly plots.
+
+\- **Scale html snapshots** to increase resolution of snapshots taken from interactive plotly plots.
+
+-----
+
+**Outputs**
+
+\- **Tabular clustering file** containing cluster information for each gene satifying filtering steps. If expression or generic data was clustered, a two columns file is generated with gene identifiers and cluster numbers with possibly additional columns containing informations used for filtering. If differential results was clustered, a similar file is returned with an additional column containing cluster numbers and differential statistics coresponding to comparisons used for filtering.
+
+\- **HTML file** to access interactive version of heatmap and screeplot through PlotLy html pages, circular plot image and tabulated clustering results. As a reminder, when the number of genes to display in heatmap/circular plot exceeds the maximum gene number parameter, a random sampling is performed for plotting efficiency. Thus, clustering displayed on heatmap/circular plot may slighlty differ from clustering information contained in tabular file as heatmap/circular plot clustering is done over a subset of genes whereas tabular file contains clustering results performed on all genes.
+
+\- **LOG file** containing information about execution. Useful especially if tool execution fails. Please attach this log file in any bug report.
