This dataset belongs to the publication: Britz S, Markert SM, Witvliet D, Steyer AM, Tröger S, Mulcahy B, Kollmannsberger P, Schwab Y, Zhen M and Stigloher C (2021) Structural Analysis of the Caenorhabditis elegans Dauer Larval Anterior Sensilla by Focused Ion Beam-Scanning Electron Microscopy. Front. Neuroanat. 15:732520. doi: 10.3389/fnana.2021.732520 FILE OVERVIEW 1. List of provided files: model files: - dauer_E1v.mod - dauer_E1v_s.mod - dauer_E2v.mod - dauer_E3v_s.mod - L1_E4v.mod image files: - dauer_E1/*.tif - dauer_E2/*.tif - dauer_E3/*.tif - L1_E4/*.tif 2. Logical links between files: - "dauer_E1v.mod" can be opened with "dauer_E1/*.tif". - Skeleton tracing of the data set Dauer_E1s from CATMAID is included in "dauer_E1v_s.mod". The data set was reduced in size both in the X- and Y-axis by a quarter. Therefore, this model should be opened without image data. - Skeleton tracing of the data set Dauer_E3s from CATMAID is included in "dauer_E3v_s.mod". This model file can be opened with "dauer_E3/*.tif". FURTHER METHOD INFORMATION We refer to the main publication and its supplementary material for detailed method descriptions. USAGE NOTES Models can be downloaded as .mod files which can be opened with the respective .tif image sequence using the IMOD user interface where applicable. IMOD is open source and can be downloaded under https://bio3d.colorado.edu/imod/ . Model objects created for measurements are included in the .mod files. Cells and structures as well as measurements are organized in object groups by their type. Structures which could not be unambiguously allocated to cells, are annotated as separate objects. Cell identities that remain ambiguous are indicated with a question mark. Note that for data set “dauer_E2v.mod” the connection trajectory of the ventral part of the IL2LL crown-like branch is ambiguous.
